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

CNTs with different wall structures—single-walled CNTs(SWCNTs),double-walled CNTs(DWCNTs), and multi-walled CNTs(MWCNTs)—were used as SAs in the experiment to investigate the single mode-locking pulse characteristics. At pump power of 10.72 W, the maximum peak power of1.312 MW was obtained with the DWCNT.展开更多
