What is the Alexandrite Laser? An Alexandrite Laser is a type of LASER (light amplification by stimulated emission of radiation) that emits high energy light through an alexandrite crystal. As the light passes through the alexandrite crystal, a beam of light 755 nm long is produced.
Note: The length of the beam of light determines how far into the skin the laser penetrates.
The color of the laser light is red.
Alexandrite Lasers can be set on Q-switching mode, which causes the laser to produce a high-energy beam of light in short pulses. This is what makes it effective for hair removal.
