摘要
利用脉宽20ps、脉冲序列能量约40mJ的锁模Nd:YAG线偏激光泵浦高压氢,在365至605nm范围内获得的70余条受激喇曼散射(SRS)谱线.经分析,这些谱线分别与氢的振动喇曼频移4156cm^(-1)和4144.2cm^(-1)的一些反斯托克斯(AS)谱线及由它们激励产生的各阶转动SRS谱线(转动喇曼频移为587cm^(-1))相对应.
More than 70 vibrational and rotational lines in the spectral range from 367 to 606 nm are observed in the stimulated Raman scattering from high pressure hydrogen Raman cell, which is excited by linearly polarized light pulse train generated with a mode locking Nd:YAG laser with 20ps pulsewidth and above 40mJ energe. These lines are the vibrational and rotational Ramanescattering lines corres-ponding to the stimulatecl vibrationa stimulated Raman shifts 4155cm^(-1) and 4144.2cm^(-1) of hydrogen, as well as to the rotational Raman shift 587cm^(-1).
