Yb 3+–Er 3+-codoped LaLiP 4O 12 glass: a new eye-safe laser at 1535 nm

Abstract

The main spectroscopic and thermal properties of Yb 3+–Er 3+-codoped LaLiP 4O 12 phosphate glasses show that they are very well adapted for use as eye-safe laser materials as a result of a comparison with different Yb 3+–Er 3+-codoped phosphate glasses.
