Glossary Thulium Laser

type of laser using thulium ions for precise medical procedures

A Thulium Laser is a type of laser that uses thulium ions as the lasing medium, typically emitting light at a wavelength of around 1927 nanometers. This specific wavelength is highly absorbed by water in biological tissues, making it effective for precise medical procedures such as skin resurfacing, hair removal, and treating certain types of alopecia by stimulating hair follicles.
