Er,Yb:Phosphate Glass

The erbium doped concentration of the LD pumped laser glass is 0.25～1.3×10²⁰cm^-³, and the light output energy ranges from microjoule to millijoule.Er³⁺, Yb³⁺ co-doped phosphate glass, with wider wavelength tuning, lower RIN and narrower laser linewidth, higher conversion efficiency and very wide pump band. It is used to make optical waveguide amplifiers and lasers. The ideal material can achieve 1535nm laser output. As a 1535nm eye-safe radiation source pumped by laser diodes, it can emit eye-safe 1535nm laser radiation, which can be directly used for laser ranging and telecommunication. Recently, it has been used in optical fiber communication to replace EDFA because of more advantages.Er-Yb Doped Waveguide Amplifier (EYDWA) is widely researched as a frontier technology.

LD pumped Er:Glass laser rangefinder modules usually are embedded into targeting system of aircrafts such as airdrones and helicopters etc...because of compact sizes and smaller weight.
