中文摘要：

利用532nm脉冲激光研究水的受激Raman散射,并利用激光诱导产生的等离子体解释了前向、后向和侧向水受激Raman散射的差异.结果表明：水与甲醇和乙醇的受激Raman阈值基本相同,大于苯、甲苯和二硫化碳的受激Raman阈值;当能量为140mJ时,出现前向Stokes和反Stokes 3 426cm-1谱线,后向和侧向出现3 400,3 268cm-1的受激Stokes谱线.

英文摘要：

Raman scattering of stimulated water was studied under the stimulation of Nd∶YAG laser at wavelength 532 nm.The Raman threshold of water is similar to that of methanol or alcohol,but is larger than that of benzene,toluene or carbon bisulfide.At an excitation laser energy of 140 mJ,3 426 cm-1 stimulated Stokes and anti-Stokes lines were found in the forward Raman scattering,the stimulated Stokes lines 3 400,3 268 cm-1 can be found in the backward and sideward Raman scattering.Owing to low Kerr constant,the threshold of the stimulated Raman of water is pretty high.The difference between the forward and backward,sideward stimulated Raman scattering of water is explained by laser induced plasma.
