四氯化碳的背向受激喇曼散射研究

Backward Stimulated Raman Scattering in CCl_4

用倍频Ｎｄ：ＹＡＧ锁模激光５３２ｎｍ泵浦ＣＣｌ４的背向受激喇曼散射，一阶斯托克斯谱线５４６ｎｍ的能量转移效率为１３％，脉宽（ＦＷＨＭ）为８ＰＳ，比泵浦激光５３２ｎｍ的脉宽４０ＰＳ明显变窄。

This paper reports backward stimulated Raman scattering in CCl4 pumped by afrequency-doubled Nd:YAG mode-locking laser 532nm. The energy conversion efficiency from532nm to I Stokes line 546urn is 13%. The Stokes pulse Width (FWHM)of 8pa was measured, itis much narrower than 40ps from pumping laser 532nm.
