laser emitting 755 nm light, used for hair removal

An Alexandrite Laser is a type of laser that emits light at a wavelength of 755 nanometers, which is in the red and near-infrared spectrum. It is commonly used for hair removal, as well as for treating pigmented lesions and vascular lesions. The laser works by targeting the melanin in hair follicles, making it particularly effective for individuals with light to olive skin tones and dark hair.
