The steady-state stimulated Raman scattering (SRS) gain with different excitation wavelengths ranging from 400 to 1100 nm of tungstate crystals, SrWO4 and BaWO4, is systematically researched. As excitation frequency is close to electronic transition frequency, molecular polarizability is not a constant, which has to be taken into account in our work. The experiment and theory agree well with each other and show that SRS gain is not only proportional to Stokes light frequency, but is also inversely proportional to biquadratic excitation frequency. 相似文献

采用腔外单次通过方式,研究了一种新型晶体YbVO4的受激拉曼散射.当抽运激光为532 nm皮秒脉冲时获得了3级斯托克斯线(558.47 nm,587.92 nm,620.67 nm)和1级反斯托克斯线(507.58 nm),测得YbVO4晶体1级斯托克斯受激拉曼散射的稳态增益系数为17.8 4±O.2 cm/Gw,受激拉曼散射的整体转换效率达到37%.实现了YbVO4晶体对355 nm皮秒激光的受激拉曼散射,观察到1级斯托克斯线(366.11 nm),根据抽运阈值得到相应的拉曼增益为29.0±0.3 cm/GW. 相似文献
