ErGlass

Erbium and ytterbium co-doped phosphate glass has a broad application because of the excellent properties. Mostly, it is the best glass material for 1.54um laser due to its eyesafe wavelength of 1540 nm and high transmission through atmosphere. It's also suitable for medical applications where the need for eye protection may be difficult to manage or diminish or hinder essential visual observation. Recently it is used in optical fiber communication instead of EDFA for its more super plus. There is a great progress in this field.

We can also produce erbium laser glass with various ions doping according to your requirement. We have three kinds of Erbium-doped glasses for different use, EAT14, Cr14 and WM4.

EAT14: Yb 3+ , Er 3+ co-doped phosphate glass, which is applicable in high repetition rate (1-6Hz) laser diode pumped 1535nm laser. High Yb 3+ doping can be realized to this EAT14 glass.

Cr14: Yb 3+, Cr:3+, Er 3+YbErbium phosphate glass for xenon lamp pumping laser device and laser range-finder

WM4: Erbium phosphate glass for ion-exchange purpose
