Er,Cr:YSGG (Erbium, Chromium doped Yttrium Scandium Gallium Garnet) provides an efficient laser crystal for generating 2800nm light in an important water absorption band. It becomes one of the most promising laser crystals recently owing to its high conversion efficiency, stable chemical properties, long fluorescent lifetime. Now Er,Cr:YSGG is widely used in dentistry, environmental researching, optical communication, remote sensing technology and military etc.
