[SAMPLE] Diode Laser
Long-wavelength semiconductor laser light is selectively absorbed by melanin in the hair follicle and converted to heat, disabling the follicle while sparing the surrounding skin.
Mechanism
Selective photothermolysis: wavelength, fluence and pulse width are chosen so the target (melanin in the hair shaft and bulb) absorbs far more energy than the surrounding tissue.
755 nm is strongly absorbed by melanin, suited to fine, light hair. 808 nm balances absorption and depth for most areas. 1064 nm penetrates deepest with little epidermal absorption, safer for darker skin.
Contact sapphire cooling keeps the skin surface cold throughout the pulse, protecting the epidermis and reducing discomfort.
