利用受激拉曼泵浦（SRP）技术建立了气态氢中v“= 1振动能级的一种有效的振动选择技术。利用光声拉曼光谱（PARS）和相干反斯托克斯拉曼光谱（汽车）研究了气态H2分子的非辐射和辐射（v″ = 0和v ″ = 1）跃迁。利用受激拉曼泵浦的光声和相干反斯托克斯拉曼光谱，估算了v ″ = 1振动能级的布居分数.
An efficient vibrationally selective technique to build-up thev″ = 1 vibrational levels in gaseous hydrogen is demonstrated usingstimulated Raman pumping(SRP). Both photo-acoustic Raman spectroscopy (PARS) and coherent anti-Stokes Raman spectroscopy (CARS) are used to study non-radiative and radiative (v″ = 0 andv″ = 1) transitions in gaseous H2molecules. The population fraction in thev″ = 1 vibrational level has been estimated using combined photo-acoustic and coherent anti-Stokes Raman spectroscopy with stimulated Raman pumping.
