Description
Er:Yb:glass Crystal Erbium And Ytterbium Co-Doped Phosphate Glass
Er, Cr,Yb: Phosphate Glass/Er,Yb phosphate glass
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 ion doping according to your requirement.
