简要描述在神光Ⅱ装置上进行的部分物理实验,为神光Ⅱ激光装置提供光学性能指标.神光Ⅱ激光装置已经能在三倍频、外转换效率高于60%的条件下常规输出三倍频能量.穿孔实验表明,蓝光(3ω0)的光束质量,特别是远场旁瓣分布质量,甚至于要好于红光(1ω0光).用100ps脉冲宽度的红光输出打爆推内爆的氘氚球靶,获得单发最高中子产额4×109个.基频线聚焦打靶,获得类Ni银X光激光饱和输出,并成功应用于激光等离子体密度测量,观测到莫尔条纹移动.

SG-Ⅱlaser facility has recently been abl e to deliver 3ω0 (blue) light with the outer conversion efficiency of ≥6 0% during its routine operation. The pinhole injection experiment this year indi cated the optical quality of the blue, especially the side lobe distribution, wa s even better than that of the red (1ω0). With the 100ps red light output , DT fuel exploding pusher experiment delivered the maximum neutron yields of 4 ×109 per shot. The red light line focus has led to the Ni like Ag X-ray lase r's saturation and the successful observation of the Moire fringe deflection wh ile the laser was applied to a separated laser plasmas. This paper presents the optical features of SG-Ⅱlaser facility and describes some of the experiments c onducted on the facility.
