Erbium and ytterbium co-doped phosphate glass has a broad application because of the excellent properties. Mostly, it is the best material for medical application 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 varios ion doping according to your requirement. We have three kinds or Erbium-doped glasses. EP6, WM4,Cr14.
