Erbium ytterbium doped glass 1535nm laser rod

Product Overview

Description

Product Description                                                                                                     

Phosphate glass doped with Er3+ and Yb3+ has wider wavelength tuning, lower RIN and narrower laser

line width, higher conversion efficiency and a very wide pumping band, it is an ideal material for making optical waveguide amplifiers and lasers.

Laser output at 1535nm can be realized in it.
