利用Nd:YAG激光器的三倍频输出(355 nm)在H2中的受激拉曼散射(SRS)获得波长在204～867 nm范围内的激光输出。当抽运能量为70 mJ时观察到四阶Stokes光和五阶Anti Stokes光，其中第一阶Stokes光(416 nm)输出能量为28.7 mJ，第二阶Stokes光(503 nm)输出能量为16 mJ，一阶Anti Stokes光(309 nm)输出能量为3 mJ。研究了H2压力和各阶Stokes光能量的关系，同时观察到环行光斑和脉宽压缩现象。

The Stimulated Raman Scattering (SRS) in H 2 pumped by the third harmonic of Nd∶YAG laser (355 nm) was investigated. The wavelength of pump laser has been shifted into 204～867 nm wavelength region. When the pump laser was operated at laser energy of 70 mJ, four orders of Stokes and five orders of anti-Stokes have been observed in this experiment. The corresponding output energy of the first order Stokes (416 nm), the second order Stokes (503 nm) and the first order anti-Stokes (309 nm) was 28.7 mJ, 16 mJ and 3 mJ, respectively. The relationships between the pressure of H 2 and energy of each Stokes were investigated. Moreover, the circle beam spot and phenomena of pulse-width compressed have been observed.
