With more energy, larger spot sizes, faster repetition rates and shorter pulse durations, the GentleMax Pro Plus is the result of decades of industry-leading innovation from the pioneers of laser-based aesthetic technology. In typical operation, the alexandrite laser produces 250-mJ fundamental pulses at 10 Hz that are first converted to ~50-mJ pulses of nominally 1.01-m light and subsequently converted to 1- to 3-mJ pulses in the 6- to 7-m wavelength range. [11] Notably, these are all long wavelength lasers that cause both photothermal and photomechanical damage to the eye. J Clin Aesthet Dermatol. The fundamental emission wavelength of this laser is 752 nm. More fluence in our largest spot sizes deliver the treatment results you demand. [5], For laser epilation, the target chromophore is melanin, causing damage to hair follicles and semi-permanent hair reduction. arrow-right-small-blue The RP Photonics Buyer's Guide contains 7 suppliers for alexandrite lasers. [4], Topical or oral ascorbic acid is often prescribed to promote fibroblast activity to minimize ocular damage. This means that relatively simple lasers can be used for such purposes. Khoury JG, Saluja R, Goldman MP. Kataoka T, Zako M, Takeyama M, et al. It is one of the most Corneal injury after carbon dioxide laser skin resurfacing. Although large alexandrite crystals can be fabricated with high optical quality, the effective optical damage threshold for large beam area can be far below the intrinsic damage threshold as can be measured on high-quality spots which are selected for particularly low scattering losses. A case of accidental ocular injury from cosmetic laser burn. Picosecond 755-nm alexandrite lasers are an effective treatment for imatinib-induced . [16], Complications have also been reported due to incidental laser exposure with use of metal corneal shields. It is also possible to pump alexandrite lasers with continuously operated Xe or Hg arc lamps, with which one can realize continuous wave operation, but also Q-switched operation with a high pulse repetition rate of e.g. In one study of 40 patients with ocular injury, 34 did not wear protective eyewear, and 5 wore goggles that were not wavelength-specific. Interested in a laser or having issues with your existing medical laser equipment? The alexandrite uses a shorter wavelength than other laser types, enabling the alexandrite to be more rapidly and intensely absorbed by melanin and the follicles of fine hairs.

We can provide a wide array of standard sized pump cavities, and can assist in the design of custom cavities for specialized applications. Diode laser Like the alexandrite laser, it is one of the most widespread systems. They can cause tissue to generate enough heat to denature proteins. Users must understand the importance of wearing proper eye protection, avoiding direct gaze, and avoiding use of the laser in a room with highly reflective surfaces such as mirrors.[27]. M1 is a highly reflecting flat mirror. The ideal wavelength would be a laser between 750 and 950 nm. Schematic of the CW dual-wavelength Alexandrite laser. Sorry, we don't have an article for that keyword! Enjoy a compact introduction to laser technology: This book soon became a bestseller among the SPIE Field Guides. Patients with darker eyes will more often report pupillary abnormalities such as iris atrophy, since the melanin in the iris absorbs most of the radiation. CLARITY II is a powerful dual wavelength platform with a wide range of parameters. AlTaleb RM, Alsharif HM, Younis AS, Alsulaiman SM, Abouammoh MA. Nd:YAG (1064 nm) The neodymium-doped yttrium aluminum garnet (Nd:YAG) laser is a long-wavelength laser that is considered to be the best for hair removal on darker skin (Fitzpatrick Types IV-VI). Adherence to optical safety guidelines for laser-assisted hair removal. [4], Rarely, ocular injuries can occur. The GentleMax Pro laser system is also a great way to expand your practice. Among them: Find more supplier details at the end of this encyclopedia article, or go to our. It is possible to make broadly wavelength-tunable lasers based on alexandrite, which sometimes reach out to well above 0.8m. For example, one patient developed bilateral bullous keratopathy following CO2 laser facial resurfacing, most likely due to overheating of the metal shields from inadequate cooling time between laser pulses. But hair removal is not the only application of this advanced technology. For full-text searches on the whole website, use our search page. Lasers Med Sci 2004;19:10511. The Alexandrite laser penetrates the skin 755nm (nanometers) deep and is suitable for skin types 1 through 4 and not recommended for darker skin types 5 and 6. The DCD is perfectly synchronized with each laser pulse, to cool the epidermis, allowing the laser energy to reach the deeper targets within the skin that are, in fact, what were trying to eradicate. A few treatments for common laser-induced injuries are discussed below. Treatment of tattoos with a picosecond alexandrite laser: A prospective trial. The alexandrite is most popularly known for its use in hair removal treatments, and is the most widely used laser technology for this purpose. x]>UR+Kr7U^j//,{H?UPyn $A +IFFw"OyVdf^]_=e\^bEe2+*{u}UEQV2+rjWjy9u9g;n]_} 'Up+0gl3\Tk-rYAYt3",?

This wavelength accurately targets a large area of the target tissue and removes excessive hair without damaging other surrounding areas. The long-pulse Alexandrite Laser has the ability of deep penetration into the dermis. Mu YZ, Jiang L, Yang H. The efficacy of fractional ablative carbon dioxide laser combined with other therapies in acne scars. [2] Patients may present weeks after receiving the laser treatment with decreased visual acuity and increased light sensitivity, along with a history of pain during the laser procedure. I would recommend the GentleMax Pro laser system to my colleagues for lots of reasons, but primarily because its so reliable and powerful. The resultant heat build-up in the hair shafts disables the hair follicles in the active growth phase which enables it to achieve effective laser hair removal.The laser is tunable, so its power can be adjusted based on the condition being treated. Alexandrite wavelength is the shortest of the three. Topics AZ It is also possible to use cavity dumping in order to achieve even shorter pulse durations of e.g. In comparison to ruby lasers, the high pulse repetition rates and average power of alexandrite lasers is beneficial for such applications. Goggles should fit snugly but comfortably, and should remain on at all times, especially during laser alignment. /|ff|@dzvk%^x~/d|]mGb& yh,[]m1;tSs&z>Dso bR>f . An alexandrite laser is one that uses an alexandrite crystal is used as the laser source or medium. 11 (11), 706 (1986). [3] Awareness of the potential ocular injuries involved can help cosmetic laser procedure providers prevent and recognize the signs of ocular injury, assist patients with making an informed decision about undergoing the procedure, and guide ophthalmologists in assessment and treatment. It is possible to apply an unstable resonator for obtaining a better trade-off between power efficiency and beam quality, but due to the low emission cross-section of alexandrite, this method does not work as well as for some other lasers; one needs to use a relatively low magnification. In the easiest case, one uses a free-running laser, producing relatively long pulses, e.g. GentleLase Laser. Hair Removal: Laser treatment has shifted hair removal from lasers, tweezers, and electrolysis to destroying the hair with energy beams. [17] A more recent case report described a patient wearing metal corneal shields who developed corneal ulceration and scarring, iris deformity, cataract, and burned eyelashes after CO2 laser resurfacing for periocular rhytides. Let a Candela product expert show you how the Gentle Pro seriescan help transform your patients - and your practice. Please do not enter personal data here; we would otherwise delete it soon. Output power 1.84 W is achieved, the highest power from blue diode pumped Alexandrite to date. However, obtaining a thorough history and physical exam can help ophthalmologists determine the appropriate treatment regimen for the patient. Venture capital firms need to find out what the potentials and limitations of certain technologies are. 1J or even several joules can be readily obtained with relatively simple laser resonators, which, however, deliver a relatively poor beam quality M2 factors of the order of 10 or larger are typically obtained. The majority of cases of ocular damage due to cosmetic exposure have occurred when safety precautions were evaded. [6], The severity of ocular injury from cosmetic lasers depends on the duration of the exposure, distance from the exposure, and the amount of energy delivered. Note, however, that it can also be used for narrowband lasing on the so-called R line, i.e., not in vibronic mode. The treatment of ocular damage due to cosmetic lasers depends on the extent and type of injury sustained. [28] In US legal cases filed after laser surgery, almost half had non-physicians listed as the primary laser operator. The alexandrite laser was originally designed to be a fixed wavelength laser, but later was developed into a tuneable solid-state laser. Alexandrite can be used to make wavelength-tunable lasers with emission ranges between 710 and 800nm. Alexandrite laser treatment. Both 755 nm and 1064 nm wavelengths treat a wide range of indications across multiple skin types - more than just hair removal! Carbon dioxide is followed by alexandrite, diode, and Nd:YAG in most common lasers implicated in ocular injury. The energy of the laser light is defined by the number of photons delivered to the target and is measured in joules (J). The Alexandrite technique is a common form of laser hair removal. It is a dual wavelength laser platform that combines the fastest and most powerful 755 nm Alexandrite laser with an equally powerful 1064 nm Nd:YAG laser for high performance treatment capabilities in terms of speed, efficacy, ease-of-use, performance, safety and patient satisfaction. However, the melanin in the epidermis competes with the hair follicle for absorption of light absorption. The Academy uses cookies to analyze performance and provide relevant personalized content to users of our website. stream The short emission wavelength of an alexandrite laser, compared with that of a Nd:YAG laser, is beneficial for removing finer hairs, but increases the risk of skin damage in the case of darker skin. Near the optimal wavelength of 750 nm, you can achieve maximum laser gain and electrical-to-optical power efficiency. This can be achieved using contact methods, such as an ice pack, or non-contact methods, such as cold air or cryogen spray. The power of laser a device defined by the amount of energy delivered over time and is measured in . The large emission bandwidth is typical for transition-metal-doped laser gain media. Technologies: alexandrite 755nm + diode 808nm + Nd: YAG 1064nm all wavelengths in 1 applicator. After applying a topical anesthetic to the eyes, corneal shields can be placed like a contact lens over the eyeball. 2006 Jun;8(2):65-8. Tentatively, a high crystal quality is more difficult to achieve in combination with a high Cr3+ doping concentration. [23] While both metal and plastic corneal shields exist, metal corneal shields are preferred, since there is reduced risk of thermal damage. arrow-right-small-blue Its really far reaching within my practice, and its pretty much in constant use. This work presents a study of a fully nonastigmatic design of a single-longitudinal-mode, wavelength-tunable, unidirectional alexandrite ring laser cavity and assessment of its performance compared to more complex laser design requiring astigmatism compensation. Green and black inks are especially easy to remove, since the base laser color ranges from red to yellow. The Gentle Pro Seriesis the gold standard for laser hair removal in all Fitzpatrick skin types.

Alexandrite lasers can be pulsed or continuous, depending on the requirements of the operation. Treatments are quick, non-surgical and provide great results. Optional Air Cooling Compatible (ACC) Handpiece Available. [12] Providers often ask patients to remove protective eyewear during eyebrow epilation or eyeliner tattoo removal, adding to the risk of laser exposure to the eye. 2 0 obj The alexandrite laser was originally designed to be a fixed wavelength laser but later was developed into a tuneable solid-state laser. Several sessions may be necessary to remove more prominent veins and spider veins. With 755 nm and 1064 nm dual wavelengths for laser hair removal, vascular and skin treatments, as well as multiple spot sizes and variable pulse duration, the Gentle Pro Series is a foundational device for all practices. Longer wavelength lasers, such as carbon dioxide, Alexandrite, Nd:YAG lasers, can penetrate deeper layers of the skin and have been the cause of more reported ocular injuries. Kirby W, Chen CL, Desai A, Desai T. Causes and recommendations for unanticipated ink retention following tattoo removal treatment. Providers often ask patients to remove their protective eyewear when targeting periorbital regions, such as during eyebrow epilation, to have easier access to the target area. Laser hair removal needs multiple sessions (3 to 6 sessions or more). <> Tunable CW alexandrite laser Abstract: Wavelength-tunable CW laser action has been obtained from solid-state alexandrite, BeAl 2 O 4 :Cr 3+ . If you need to face many different clients when doing permanent hair reduction treatment, take a look at this cutting-edge machine. It has two wave lengths, the 755 nm Alexandrite and the 1064 nm Nd:YAG. Extreme caution is recommended in tanned or darker skinned patients, as the laser can also destroy melanin, resulting in white patches of skin. His analytic mind allows him to develop a balanced perspective, taking into account all relevant aspects. [1], When used at low fluences, diode lasers are 22%-59% effective at long-term hair removal and has one of the best safety profiles for use in darker skin tones (Fitzpatrick Types III-V). Depending on the area, the skin will remain completely clean and smooth for around 6 to 8 weeks after treatment; it is time for the next session when fine hairs start to grow again. It has energy level structure similar to the energy level structure of Ruby laser. In most cases, flash lamps are used; pump pulse energies are typically of the order of hundreds of joules or several kilojoules, and the pulse repetition rate is normally quite low for example, 10Hz or 30Hz. This results in the release of a photon of light as it returns to a stable state. It is considered a red light laser. U. Demirbas and F. X. Krtner, Alexandrite: an attractive thin-disk laser material alternative to Yb:YAG?, J. Opt. Therefore, the architecture of a master oscillator power amplifier (MOPA) can offer better performance, of course at the cost of a higher complexity. subscribe to receive our company's latest news, product and technology updates, and upcoming events. [25] In addition, risk of corneal abrasion from wearing corneal shields is possible, but can be minimized with appropriate lubrication. Note that with this approach, it is also possible to do spectral filtering between oscillator and amplifier, so that one can obtain and mission with a smaller linewidth. For laser epilation, the target chromophore is melanin in the hair follicle. <>/XObject<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 612 792] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> Foveal choroidal neovascularization secondary to accidental laser exposure in a dermatologist: A case report. A carefully designed and complex ring resonator with several functional components is combined with an innovative pumping scheme with high-power red laser diodes. <> One study found that plastic shields melted or caught fire when radiation from long-wavelength Nd:YAG and carbon dioxide lasers were applied. For the most part, laser systems for this purpose range from the 694-nm ruby laser at the short end of the spectrum to the 755-nm alexandrite laser and 800- to 810-nm diode laser in the middle of the spectrum and the 1064 . Therefore, this approach is relatively seldom used. 2004 Apr;30(4 Pt 1):494-7. Diode lasers use a longer wavelength (usually around 810nm). (The absorption occurs mostly in melanin, which occurs in hair but also in dark skin, and less in hemoglobin.). [4] For corneal lesions involving the endothelium, surgical intervention with corneal transplantation may be necessary, since endothelial involvement can lead to bullous changes, corneal thickening, or vision loss. Procedures can be performed by licensed physicians, mid-level practitioners, and aestheticians, generally with self-limited side effects such as mild pain, redness, and edema. In the laser and photonics industry, it is often essential to obtain competent evaluations of certain technologies: Involving a top expert such as Dr. Paschotta into technology evaluations can have many advantages: Just contact RP Photonics to find out what we can do for you! This can make it difficult to efficiently extract the stored energy in a laser crystal; note that the applicable intracavity laser intensities are limited by optical damage. 1 0 obj Occurrence of side effects in 2% of dark colored patients treated with Alexandrite lasers. . Alexandrite lasers are chromium-doped solid-state lasers based on the crystalline gain medium alexandrite, which is Cr3+:BeAl2O4. Alexandrite laser treatment codes and concepts, Facial vein and vascular birthmark treatments, Laser Treatment of Benign Pigmented Lesions, Complications of Dermatologic Laser Surgery, Generally ineffective for light coloured hair, but useful for treating dark hair in patients of, The typical settings employed include pulse durations of 2 to 20 milliseconds and fluences of 10 to 40 J/cm. Arch Dermatol 2012; DOI: 10.1001/archdermatol.2012.2894. . No need to buy multiple lasers to treat multiple targets. Alexandrite was one of the first few vibronic laser gain media, discovered in the late 1970s. with durations of hundreds of microseconds or even many milliseconds. ND yag laser like alexandrite laser wavelength is 755nm and 1064nm. Selective photothermolysis: precise microsurgery by selective absorption of pulsed radiation. Comparison of long-pulsed alexandrite and Nd:YAG lasers, individually and in combination, for leg hair reduction: an assessor-blinded, randomized trial with 18 months of follow-up. Mostly used for skin types I-III. For example, such lasers are used for hair removal, for removing tattoos and for treating visible leg veins and pigmented lesions. The Laser Warehouse has been providing high quality pre-owned medical laser equipment at affordable prices for over a decade. Its widely regarded as the gold standard for laser hair removal and I use it very often for that and also for other, lesser known indications, such as pigmentary lesions and vascular lesions, like venous lakes, telangiectasia, and leg veins. [26] While this may not be necessary in cosmetic laser procedures, cooling of periorbital regions can help protect against epidermal injury. Higher fluences, larger spot sizes and shorter pulse durations all point to the power of the new GentleMax Pro Plus platform. Tunable alexandrite lasers Abstract: Wavelength tunable laser operation has been obtained from the solid-state crystal alexandrite (BeAl 2 O 4 :Cr 3+ ) over the continuous range from 701 to 818 nm. several tens of kilohertz or mode-locked operation. Alexandrite is the leader of a class of tunable solid-state laser materials. In dermatological applications, high intensity pulses from a free-running laser are normally applied to large areas of skin. The medium amplifies the light of a particular wavelength as it passes through it. Short 2 ms pulse durations offer new, finer hair treatment capabilities. Furthermore, Bells phenomenon (where the eye naturally rolls upward upon eyelid closure) increases the risk of damage to the iris by bringing anterior eye structures closer to the lasers radiation range. Nouri K, Chen H, Saghari S, Ricotti CA Jr. Dermatol Surg. Based on alexandrite (Cr:BeAl2O4), the most robust, tunable solid-state laser medium, the PAL laser system can tune continuously or operate at any fixed wavelength. There are natural alexandrite gemstones, but material for laser crystals is artificially produced and grown in monocrystalline form with high crystal quality, using a modified Czochralski growth method. DermNet does not provide an online consultation service. (Note that the upper-state lifetime is less relevant in the case of pulsed pumping and rapid energy extraction.). Laser hair removal: A review. DOUBLE WAVELENGTH PLATFORM. In many cases, roughly 10cm long cylindrical laser rods with a diameter of e.g. Lin LT, Liang CM, Chiang SY, Yang HM, Chang CJ. Alexandrite laser was operated for the first time as a three level laser in 1973 at a wavelength of 680 [nm]. We report the first ever demonstration of a wavelength-locked Alexandrite laser using a volume Bragg grating (VBG) as a wavelength-selective mirror. Maybe there are some hidden problems? | All Rights Reserved. This is a tremendous option to have. [13][20] [21] [22], Inappropriate use of alexandrite lasers for hair removal has led to reports of subfoveal and intraretinal hemorrhages. We specialize in alexandrite, Nd:YAG, Er:YAG and CTH:YAG gain media. [29] This suggests that mid-level providers or aestheticians comprise a large proportion of cosmetic laser operators. Note: The length of the beam of light determines how far into the skin the laser penetrates. Enhanced by several years of research and development, it features a broad wavelength tuning range of 710 - 800 nm with the capability to store and efficiently extract multi-joule pulses of energy. In the case of hair removal, the light from a long-pulse laser is preferentially absorbed in the hair shafts, and the resulting heat damages these hair shafts and the surrounding hair follicles (selective photothermolysis). Alexandrite laser is a 755 nm wavelength. The risk increases when procedures are performed in the periorbital region, where the chance of a misdirected laser at the eye with inadequate safety precautions is higher.[2]. It is possible to optimize laser resonators for substantially higher beam quality, but this requires more sophisticated laser resonator designs and normally leads to substantially lower output pulse energies and power conversion efficiencies. [22] Anterior segment examination is expected to be within normal limits. Ocular Complications After Laser or Light-Based Therapy-Dangers Dermatologists Should Know [published online ahead of print, 2021 Mar 9]. Lin CC, Tseng PC, Chen CC, Woung LC, Liou SW.
