Abstract
LD end-pumped passively Q-switched Nd:YLF/SrWO4/Cr4+:YAG Raman laser for multi-Raman-modes is investigated for the first time. Based on the main Raman mode (923 cm−1), the maximum average output power of 0.462 W is achieved for 1st Stokes laser at 1159 nm. When the pumping power is 2 W, the maximum optical conversion efficiency of 17.4% is obtained with the pulse repetition frequency of 6.6 kHz and pulse width of 21 ns. By selecting an appropriate cavity mirror to suppress stimulated Raman scattering process of main Raman mode, SRS conversion of the minor mode (334.5 cm−1) of SrWO4 crystal is realized separately for the first time in intracavity Raman laser. The maximum output power at 1085 nm obtained is 0.111 W. In experiments, multi-pulse phenomena of Stokes laser output with the main Raman mode (923 cm−1) are observed, which are more obvious for smaller initial transmittance of saturable absorber and higher reflectivity of output coupler.
