Erbium Doped Phosphate Glasses For LD Pump
Er3+/Yb3+ co-doped phosphate glass — as the 1540nm eye-safe
radiation sources pumped by LD which can emit eye-safe 1540nm laser
radiation directly used in laser ranging finder and
telecommunication communication
As an eye-safe wavelength laser, 1540um ,Er3+/Yb3+ co-doped phosphate glass lasers have attracted much attention for their compactness and low cost, such as laser generation and signal amplification because the wavelength of 1540nm is just at the position of the eye-safe and the fiber optic communication window. 1540nm lasers have used in ranging finder, radar, target recognition. Er3+/Yb3+ co-doped phosphate glass cooperate with passive Q-Switch crystal -co:spinel to get 1540nm pulse solid-state laser.
