Stimulated Raman scattering of LiIO_3 crystal
By the ultra-cavity single-pass configuration,stimulated Raman scattering(SRS) of LiIO3 crystal was realized.When the pump source was a 532 nm picosecond laser,three Stokes lines(556.07,582.30,611.76 nm) and one anti-Stokes line(509.57 nm) were observed,and the frequency shifting was calculated to be 820 cm-1.The SRS thresholds and Raman gain coefficients for different scattering lines were measured,and the total conversion efficiency reached 56%.Picosecond,external resonator Raman laser was realized based on LiIO3 crystal,the total conversion efficiency for dual-wavelength output was 27%,and the largest output energy was 1.4 mJ.
