神光-Ⅱ实验装置经过一段时间的改进,特别是在光束质量方面的提高,填充因子已经达到50%左右,光束的空间分布比较均匀,又使用新的N31型磷酸盐钕玻璃,荧光寿命从250 μs提高到330 μs,使其增益能力大大地提高,6片N31型磷酸盐钕玻璃片与厚度相同的8片N21老型磷酸盐钕玻璃片相比,增益增加约10%左右.

After Shenguang-Ⅱ system is improved particulaly on beam quality the figure of filler reaches about 50%. The beam spatial distrubution is uniform. New N 31 type phosphate glass are used, the fluorescence life is increased from 250 μs to 330 μs. The gain ability is increased. The gain of 6 disks N 31 type phosphate glass compared with the gain of 8 disks N 21 type phosphate glass, the gain increased about 10%.
