| Abstract: | 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. |
