Stimulated Raman scattering of 35-ps pulses in BaWO(4) crystal was studied. The second harmonic of a Nd:YAG double-mode-locked laser system was used as a pump radiation source. The first Stokes conversion efficiency reached 38% in a single-pass setup and 85% in a double-pass setup. The second Stokes was generated with 20% (single-pass) and 50% (double-pass) conversion efficiency. Measurement of the temporal profiles of pump and first Stokes radiation with picosecond resolution was performed. The obtained conversion efficiency data were compared with the a plane-wave numerical model. BaWO(4) crystal can be considered an efficient Raman-active material for utilization in picosecond solid-state laser systems.
研究了BaWO(4)晶体中35皮秒脉冲的受激拉曼散射。Nd:YAG双锁模激光系统的二次谐波用作泵浦辐射源。在单程装置中,第一斯托克斯转换效率达到38%,在双程装置中达到85%。第二斯托克斯的产生效率为20%(单程)和50%(双程)。对泵浦光和第一斯托克斯辐射的时间轮廓进行了皮秒分辨率的测量。将获得的转换效率数据与平面波数值模型进行了比较。BaWO(4)晶体可被视为用于皮秒固态激光系统的高效拉曼活性材料。
