The Erbium Laser is a type of solid-state laser that uses erbium as its active medium. It emits light at a wavelength of 2940 nanometers, which is highly absorbed by water. This property makes it particularly effective for medical and cosmetic procedures, such as skin resurfacing and dental treatments. In addition to its medical applications, the Erbium Laser is also used in various industrial processes, including material processing and engraving. Its precision and ability to minimize thermal damage make it a valuable tool in both healthcare and manufacturing sectors.
