Synthesis and Spectroscopic Investigations of Yb3+-Er3+-Codoped LaLiP4O12 Glasses Relevant for Laser Applications.

Abstract

We are involved in Yb3+-Er3+-codoped phosphate glass research for eye-safe laser source near 1535 nm, wavelength corresponding to the 4I13/2→4I15/2 Er3+ transition [1]. Undoped and doped glasses of the composition La2O3-Li2O-P2O5, with LaLiP4O12 formula, have been synthesised.
