Abstract
High-order Stokes wave was observed in an x-cut KTP crystal based on stimulated Raman scattering (SRS) pumped by a passively Q-switched Nd:YLF laser with a Cr4+:YAG saturable absorber. Output spectra including the fundamental wave at 1047Â nm and six Stokes wavelengths at 1077Â nm, 1110Â nm, 1130Â nm, 1143Â nm, 1164Â nm, 1180Â nm based on two Raman frequency shift at 267.4Â cmâ1 and 693.0Â cmâ1 were obtained simultaneously. We also detected green light generation with output power of 12Â mW from self frequency mixing in the KTP crystal. The maximum total output power reached 452Â mW at the repetition frequency of 8.1Â kHz, corresponding to the optical-to-optical conversion efficiency of 4.61% and pump-to-Raman conversion efficiency of 3.6%.
