| 摘 要： | 采用腔外单次通过方式，测量了LiIO3晶体在532 nm皮秒脉冲下的受激拉曼散射。实验中观察到3级斯托克斯线（556.07,582.30, 611.76 nm）和1级反斯托克斯线（509.57 nm），由此可计算出其频率间隔为820 cm-1。测量了LiIO3晶体各级拉曼散射谱线的阈值和增益系数，受激拉曼散射的整体转换效率达到56%。基于LiIO3晶体实现了皮秒外腔式拉曼激光器的运转，双波长输出总转换效率为27%，最大输出能量1.4 mJ。

| Abstract: | 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. |
