摘要
本文采用对撞脉冲锁模Nd:YAG激光器输出10ps脉冲串,经KTP非线性晶体腔外倍频,泵浦喇曼介质为二甲亚砜(DMSO)液体.实验研究了不同透镜焦长、焦点位置及不同喇曼介质氏度对瞬态受激喇曼散射的影响,获得了能量转换效率分别为45.6%和10.5%的前、后向一阶斯托克斯-喇曼散射光,并对实验结果进行了讨论.
10 picosecond pulses from a colliding pulse mode- locked Nd : YAG laser pass through a KTP crystal and pump DMSO Raman medium. The effect of lenses with different focal length, focal point location and the length of Raman medium on the transient stimulated Raman scattering studied experimentally. Energy conversion efficiency of 45. 6% and 10. 5% for the forward and backward first Stokes Raman sacttering are obtained respectively. The experimental results are discussed.
