摘要
利用Nd∶YAG固体激光器四倍频输出 (2 6 6nm)在高压H2 中的受激喇曼散射获得多波长的激光输出。当泵浦能量一定时 ,通过改变H2 压力得到了最佳的能量输出 ,2 99nm波长的激光能量为 3mJ,341nm波长的激光能量输出为 6 .1mJ ,398nm波长的激光能量输出为 2 .8mJ ,2 39nm波长的激光能量输出为 0 .8mJ,同时在 4 77nm ,5 95nm ,2 18nm ,2 0
The stimulated Raman scattering (SRS) in H 2 pumped by the fourth harmonic of Nd∶YAG laser (266nm) is investigated.The wavelength of the pump laser has been shifted into 200nm～595nm wavelength region.When the pump laser is operated at laser energy of 22mJ,five orders of Stokes and three orders of anti-Stokes have been observed.The corresponding output energy of the first order Stokes (299nm),the second order Stokes (341nm) and the first order anti-Stokes (239nm) was 3mJ,6.1mJ and 0.8mJ respectively.The relationships between the pressure of H 2 and energy of each Stokes were investigated.Moreover,the circle beam spots have been observed.
