Diode-Pumped c-Cut Nd:Lu_0.99La_0.01VO₄ Self-Stimulated Raman Laser at 1181 nm

The self-stimulated Raman laser operation of a Nd:Lu_0.99La_0.01VO₄ new crystal is presented. A 0.3 at.% Nd doped Lu_0.99La_0.01VO₄ crystal in dimensions 3×3×20 mm³ is adopted as the self-stimulated Raman crystal. At a pulse repetition frequency of 14 kHz, average output powers of 240 mW for the first Stokes light at 1181 nm and 660 mW for the fundamental light at 1068 nm are obtained under an incident pump power of 5.5 W. The pulse widths of the first Stokes light and fundamental light are about 15 and 25 ns. The slope efficiencies are about 12.7% and 18.8% with respect to the incident pump power.
