Product Description

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.

Stimulated emission cross section

Narrow fluorescence line

High pump efficiency

Short fluorescence lifetime

Low oscillation threshold


Using Glass

WM4: Erbium phosphate glass for ion-exchange purpose;

EAT14: Yb3+, Er3+ co-doped phosphate glass, which is applicable in high repetition rate(1-6Hz) laser diode pumped 1535 laser. High Yb3+ doping can be realized in this EAT14 glass.



Waveguide amplifier


@1550nm: Fiber has minimum dispersion and small loss






LD pumped solid-state laser





Eye-safe Laser Rangefinder

Direct output 1.54μm human eye laser, suitable for handheld or vehicle laser rangefinder
