Laser action in Nd(3+)-doped lanthanum oxysulfide powders

Opt Express. 2012 Oct 8;20(21):23690-9. doi: 10.1364/OE.20.023690.

Abstract

We have investigated the stimulated emission properties of Nd(3+) doped La(2)O(2)S powders at room temperature as a function of pumping energy density, excitation wavelength, and Nd(3+) ion concentration. The absolute stimulated emission energy has been measured. Expressions for the slope efficiencies and lasing thresholds as a function of rare earth concentration and pumping wavelengths, which qualitatively agree with experimental observations, are discussed.
