本文报道六路亚毫微秒钕玻璃激光系统近年研究进展概况。该系统经改进、提高后其输出脉宽分四档可调;～100ps、～250ps、～400ps及～1ns;输出波形基本可控制为光滑波形或调制波形;输出光谱宽度可调区为≤1或20～30;在输出脉宽～250ps时,单路输出能量控制在5～10J;在输出脉宽～1ns时,能量控制在10～15J。最后给出该系统总体运转稳定性的结果。

The paper reports the pregress in our six beam subnanosecond Nd-glass high power laser facility. Now the improved laser system is able to generate pulses with the following parameters: Pulse width can be selected from four ranges: 100 ps, 250 ps, 400 ps and 1ns; Pulse shape is controllable basically either in smooth mode or in modulated mode; Spectrum width is tunable in the ranges of ≤1A and 20～30A; Output energy can be also chosen in the way that for single beam it is 5～10 joules with pulse width of 250 ps and is 10~15 joules with pulse width about 1 ns. The experimental data of long period operaiion stability are given in the end part of the paper.
