| 摘 要： | 研究了布里渊放大器Stokes出射光束的发散角随抽运功率密度的变化规律以及与种子光束和抽运光束发散角的关系。抽运功率密度的变化对Stokes出射光束的发散角几乎没有影响,通过控制Stokes种子光束的发散角可以获得高光束质量的输出激光。

| Abstract: | The divergence of Stokes output versus power density of pump in the Brillouin amplifier was experimentally studied and the relations of divergence among Stokes output, Stokes seed and pump were also experimentally studied. The change of pump power density hardly affects the divergence of Stokes output, and high quality Stokes output could be obtained by controlling the divergence of Stokes seed beam. |
