The alexandrite laser emits high energy light through an alexandrite crystal producing a beam of light which is 755 nm long. it is one of the most effective laser for thin or fine hair that many of the other types of laser cannot eliminate.. Lasers used in alexandrite laser hair removal technique. there are two modes of operation in the alexandrite laser hair removal technique and these depend on the type of laser being used. q-switched laser. the output of this type of laser machine is pulsed.. An alexandrite laser (755 nm, 10 to 20 ms, 18-mm spot size) with a dynamic cooling device™ (dcd™) cooling system was used for hair removal in 22 patients (16 male and 6 female patients) after.
To achieve permanent hair reduction, the laser system must be able to effectively treat all skin types, while providing maximum skin protection. lighter skin types are mainly treated with 755nm (alexandrite) or 805 nm (diodes laser) while darker skin types are mainly treated with 1060/1064 nm, which is available on both diode and solid state. Its alexandrite laser emits high-energy light in longer wavelengths than those of other lasers, so it can destroy deeper hair follicles. it can be used on any part of the body, but popular treatment areas include the legs, underarms, bikini zone, face, chest, and back.. Currently, lasers with a variety of wavelengths are used for hair removal, ranging from the 695-nm ruby laser at the short end to the 1064-nm nd:yag laser at the long end. 10 while shorter wavelengths are ineffective in achieving the desired long-term hair removal, longer wavelengths are too close to the light absorption rates of oxyhemoglobin.
