Quick Details
Specifications
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.
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.
