【摘要】 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 5 0 %左右 ,光束的空间分布比较均匀 ,又使用新的N3 1型磷酸盐钕玻璃 ,荧光寿命从 2 5 0 μs提高到 330 μs,使其增益能力大大地提高 ,6片N3 1型磷酸盐钕玻璃片与厚度相同的 8片N2 1老型磷酸盐钕玻璃片相比 ,增益增加约 10 %左右更多还原

【Abstract】 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%.更多还原
