Erbium,Ytterbium,Chromium co-doped phosphate glass laser crystal for eye-safe laser applications

Erbium doped phosphate glass in one of the best working media of solida state laser with eye-safe beam wavelenth 1535nm,

which is widely applied for long distance both civiliant and military rangfinders (LRFs ) because of better ability of transmission in the atmosphere but is safe for eyes of human. It is suitable for applications for ranging, medical treatment, scientific research and other purposes.As the raw material for making  solid gain medium crystal for flash lamp pumped lasers and DPSS laser, the erbium-doped concentration is 0.13cm³～0.25cm³, and the light output energy ranges from millijoule to joule level.
