摘　　要：利用 SBS作为相位共轭镜 ,对宽带 Kr F自由振荡激光器的光束质量进行了改善。在 Kr F激光能量为36m J,脉宽为 13.7ns,束散角为 9.5倍衍射限的条件下 ,获得输出能量为 2 0 .8m J,脉宽为 4 .3ns,束散角为 6.4倍衍射限的高光束质量宽带 KrThe beam quality of broadband free oscillated KrF laser was investigated utilizing SBS as phase-conjugation-mirror in this paper. Broadband 6.4X diffiraction-Limited KrF with energy of 20.8mJ and pulse duration of 4.3ns was obtained while the 9.5X diffraction-Lmited pump KrF laser with energy of 36mJ and pulse duration of 13.7ns was used.
