A 0.3at.% Nd doped Lu0.99La0.01VO4 crystal in dimensions 3 × 3 × 20 mm^3 is adopted as the self-stimulated Raman crystal. At a pulse repetition frequency of 14kHz, average output powers of 24OmW for the first Stokes light at 1181 nm and 660mW for the fundamental light at 1068nm 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 25us. The slope effieiencies are about 12. 7% and 18.8% with respect to the incident pump power.展开更多

With an incident pump power of 10 W, the Q-switched laser with average power of 430 mW for 1.17 μm, pulse width of 270 ps, repetition rate of 13 kHz and the first order Stokes conversion efficiency of 4.3% is obtained. The Q-switched pulse width can be the narrowest in our research. In addition, the yellow laser at 0.58 μm is also achieved by using the LiB_3O_5 frequency doubling crystal.展开更多
