Alexandrite laser treatment | 合法醫療器材資訊網

A LASER[1] (light amplification by stimulated emission of radiation) works by emitting a wavelength of high energy light, which when focused on a certain skin condition will create heat and destroy diseased cells. Wavelength is measured in nanometres (nm).

Various kinds of lasers are available for use in skin surgery. They are differentiated by the medium that produces the laser beam. Each of the different types of lasers has a specific range of utility, depending on its wavelength and penetration. The medium amplifies the light of a particular wavelength as it passes through it. This results in the release of a photon of light as it returns to a stable state.

The duration of the light pulses affects the laser’s clinical applications in skin surgery.
