Erbium and ytterbium co-doped phosphate glass has a broad application because of it's excellent properties. Mostly, it is the best glass material for 1535nm laser due to its eye-safe wavelength of 1535nm and high transmission through atmosphere, it is also suitable for medical applications where the need for eye protection may be difficult to manage or diminish or hinder essential visual observation. We can also produce erbium laser glass with various ions doping according to your requirement.

Applications:

WM4: Erbium phosphate glass for ion-exchange purpose. Cr14: Erbium phosphate glass for xenon lamp pumping laser device and laser range-finder EAT14: Yb3+, Er3+ co-doped phosphate glass, which is applicable in high repetition rate (1-6Hz) laser diode pumped 1535nm laser. High Yb3+ doping can be realized to this EAT14 glass. CrE5: CrE5 is for large energy output application. The glass rod of CrE5 can work safely at 1Hz repetition after surface strengthing treatment at over 10J output level.
