[13], Laser parameters, patient profile (eye, skin, and hair type), and safety protocols all play a role in the outcome of laser treatment. Mainster MA, Stuck BE, Brown J Jr. Assessment of alleged retinal laser injuries. Lett. The wavelength of high energy light emitted by the laser is converted to heat energy and this damages the specific target area. Laser use for cosmetic purposes relies on the principle of selective photothermolysis, in which specific wavelengths of light can be targeted toward a chromophore or structure while sparing the surrounding tissue. Picosecond 755-nm alexandrite lasers are an effective treatment for imatinib-induced . Wavelength is measured in nanometres (nm). Without enough energy in each pulse, there is no pigment fragmentation and no tattoo removal. (Note that the upper-state lifetime is less relevant in the case of pulsed pumping and rapid energy extraction.). The Laser Warehouse has been providing high quality pre-owned medical laser equipment at affordable prices for over a decade. This page was last edited on January 25, 2023, at 12:21. Alexandrite Laser Hair Removal. Ocular complications after cosmetic periocular diode laser application to the eyelids. The Alex rod is mainly used for applications such as dermatology, Tentatively, a high crystal quality is more difficult to achieve in combination with a high Cr3+ doping concentration. 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. Huang A, Phillips A, Adar T, Hui A. Ocular Injury in Cosmetic Laser Treatments of the Face. Am. Widder RA, Severin M, Kirchhof B, et al. 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. [11] Notably, these are all long wavelength lasers that cause both photothermal and photomechanical damage to the eye. All rights reserved. All other trademarks are the property of their respective owners. It is an Alexandrite laser, which means it uses alexandrite crystal as its source. The GentleMax Pro laser system is also a great way to expand your practice. These include Ta2 Eraser (Light Age, California, USA), Apogee (Cynosure, Massachusetts, USA) and Accolade (Cynosure, MA, USA), Individual machines may be specially designed to focus on specific skin problems. [1] For facial redness, scars, and warts, short wavelength lasers are often used, such as the potassium titanyl phosphate laser (532 nm) and pulsed dye laser (585-595 nm). Alexandrite laser treatment is used to remove black, blue and green pigment. This together with the strong birefringence of the material makes it easy to obtain linearly polarized emission with low depolarization losses. The fundamental emission wavelength of this laser is 752 nm. Medscape Reference pages on lasers including alexandrite. Particularly for pulsed operation well away from the optimum wavelength region around 750nm, the laser efficiency can be substantially reduced due to that problem. 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. Lasers Med Sci 2004;19:10511. Khoury JG, Saluja R, Goldman MP. Laser hair removal: A review. The ideal wavelength would be a laser between 750 and 950 nm. This laser is recommended for persons with light skin tones since it is believed to hurt somewhat less than other lasers. It has energy level structure similar to the energy level structure of Ruby laser. Often laser hair removal brings patients into my practice; but the way you keep them in your practice, is number one, you provide a great service, so that means you deliver long lasting hair reductions. We report the first ever demonstration of a wavelength-locked Alexandrite laser using a volume Bragg grating (VBG) as a wavelength-selective mirror. The colour of the tattoo and the depth of the pigment influence the duration and the outcome of the laser treatment for tattoo removal. Alexandrite is the leader of a class of tunable solid-state laser materials. [11] Patients with higher initial visual acuity are also more likely to report ocular issues, likely due to the increased chance of noticing acute vision changes.[11]. They are differentiated by the medium that produces the laser beam. Specifications: Wavelength: 755 Pulse width: 2-20 Fluence: 10-40 Spot size: 5-10 Repetition rate: 1-5 Devices available: Three different alexandrite lasers are available:Apogee-40 (Cynosure), EpiTouch Alex (formerly ESC Sharplan, now Lumenis.) Bruising affects up to 10% of patients. Saedi N, et al. The possible peak power is much higher in that regime, although the power conversion efficiency is significantly lower. Corneal shields are especially important for the patient to wear when protective goggles are unfeasible, such as during eyeliner tattoo removal or eyelash cauterization. The Apogee+ boasts higher power and speed, providing practitioners with up to 20 J/cm2 at an 18 mm spot size and 2 Hz. Note, however, that it can also be used for narrowband lasing on the so-called R line, i.e., not in vibronic mode. . 2004 Apr;30(4 Pt 1):494-7. As far as they get accepted by the author, they will appear above this paragraph together with the authors answer. 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). In particular, laser-assisted hair removal is a commonly performed cosmetic procedure for semi-permanent hair reduction. To remove a full color tattoo effectively you need at least three laser wavelengths. Frdric St-Denis (born 1986), Canadian hockey player. The GentleMax Pro laser is a true work horse in my practice. [22] Macular SD-OCT would reveal hyper-reflective lesions. Periocular CO. Balyen L. Inadvertent macular burns and consecutive psychological depression secondary to Alexandrite laser epilation: A case report. Traumatic macular hole secondary to a Q-switch Alexandrite laser. Of course, 755 nm wavelength can penetrate deep into the dermis and can be used for dermal pigmentation and tattoo treatment. Alexandrite can be used to make wavelength-tunable lasers with emission ranges between 710 and 800nm. [29] This suggests that mid-level providers or aestheticians comprise a large proportion of cosmetic laser operators. arrow-right-small-blue A dual-wavelength continuous-wave (CW) and passively Q-switched alexandrite laser based on a MoS2 saturable absorber (SA) operating at 736.7 nm and 752.8 nm with a simple and compact 18 mm plano-plano resonator is reported. Treatment of tattoos with a picosecond alexandrite laser: A prospective trial. The wavelength of picosecond alexandrite laser is 755 nm, which is effective for epidermal pigmentation treatment due to the epidermal bypass effect and is the safest wavelength (refer to Sect. Methods to overcome poor responses and challenges of laser hair removal in dark skin. Intense Pulsed Light Eyebrow Epilation and Iris Lesion. Applications: permanent hair removal on all skin tones and hair colors Only 3 ~ 5 courses are needed to get an ideal result! Clinical comparison of four hair removal lasers and light sources. For laser epilation, the target chromophore is melanin in the hair follicle. Figure 3. Maybe there are some hidden problems? The US Food and Drug Administration (FDA) has approved a range of alexandrite laser machines emitting infrared light (wavelength 755 nm) for various skin disorders. 21 (15), 1150 (1996). Semin Cutan Med Surg. arrow-right-small-blue Kataoka T, Zako M, Takeyama M, et al. Alexandrite laser is a solid state laser in which Chromium ions (Cr +3 ), at the amount of 0.01-0.4 %, are embedded in BeAl 2 O 4 crystal . The laser treatment involves the selective destruction of ink. The alexandrite is especially effective on fine and light hair, since the laser energy is so easily absorbed by the melanin pigment in hair. Among them: Find more supplier details at the end of this encyclopedia article, or go to our. [4], Topical, injectable, implantable, or systemic corticosteroids are indicated for laser-induced retinal injury. Kirby W, Chen CL, Desai A, Desai T. Causes and recommendations for unanticipated ink retention following tattoo removal treatment. [23] While both metal and plastic corneal shields exist, metal corneal shields are preferred, since there is reduced risk of thermal damage. As the light passes through the alexandrite crystal, a beam of light 755 nm long is produced. Please do not enter personal data here; we would otherwise delete it soon. A common laser combination is 1064 nm (Nd:YAG), 532 nm (frequency doubled Nd:YAG) and 755nm (alexandrite). [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). several tens of kilohertz or mode-locked operation. Immediately following treatment, an ice pack may be applied to soothe the treated area. Alexandrite laser for the treatment of port wine stains refractory to pulsed dye laser. Higher fluences, larger spot sizes and shorter pulse durations all point to the power of the new GentleMax Pro Plus platform. It continues to be my go-to laser for hair removal, no matter how many hair removal lasers I try. [25] In addition, risk of corneal abrasion from wearing corneal shields is possible, but can be minimized with appropriate lubrication. Many patients who come in and experience hair removal with the system, then also become interested in treating other cosmetic concerns. *Individual Results May Vary [19], Diode laser epilation to the eyelid area has led to reported cases of nuclear cataracts and iris atrophy. 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. The Gentle Pro Series includes: GentleYag Pro, GentleLase Pro, GentleMax Pro, and GentleMax Pro Plus. Alexandrite was one of the first few vibronic laser gain media, discovered in the late 1970s. Selective photothermolysis: precise microsurgery by selective absorption of pulsed radiation. Tattoo Removal: Its precision and ability to absorb melanin so easily has made the alexandrite an effective solution for tattoo removal. The patient, provider, and observers are all at risk for ocular damage due to incidental exposure of lasers. [18], While there are numerous case reports describing the initial symptoms and clinical findings of patients with ocular injury following a cosmetic laser procedure, there is little consensus on the long-term sequelae and outcomes of these patients. via e-mail. Sufficient energy must be delivered during each laser pulse to heat the pigment to fragmentation. The machine can be adjusted for various skin types and hair colors to better serve a variety of skin tones and hair colors.
