Cr,Er:YSGG (Chromiun and Erbium doped Yttrium Scandium Gallium Garnet, Cr,Er:Y3Sc2Ga3012)
Cr,Er:YSGG (Chromium and Erbium doped Yttrium Scandium Gallium Garnet) is a type of solid-state laser material. The addition of chromium and erbium ions to the yttrium scandium gallium garnet (YSGG) crystal matrix creates a laser active medium that can produce light at a specific wavelength, typically in the mid-infrared range (around 2.8 μm). These lasers are used in various industrial and medical applications, such as laser surgery, laser material processing, and spectroscopy.
