| 摘 要： | 报道准连续６０Ｗ线列阵二极管激光器侧面泵浦的Ｎｄ：ＹＡＧ激光器及用ＬｉＦ：Ｆ２－晶体作饱和吸收体的被动调Ｑ激光器。在重复频率为１０Ｈｚ，泵浦脉宽为４００μｓ，峰值功率为６０Ｗ的泵浦速率下，激光弛豫振荡每周期输出的能量为３ｍＪ，相应的全光光效率为１２．５％。在调Ｑ方式下运转时，每周期可得到３个能量为４００μＪ，脉宽为１１．５ｎｓ的脉冲。通过腔结构的调整，实验中还获得能量为２００μＪ的单横模的单脉冲输出。通过数值模拟讨论了脉冲的形成过程和脉冲特性，并对进一步的研究工作提出了改进方案。

| Abstract: | Passive Q-switched laser has been achieved in Nd:YAG transversely pumped by a Q-CW 60 W laser-diode-array. While the laser diode was working on a repetition rate of 10 Hz at power as high as 60 W and pulse width of 400 μs, a free running stable oscillation with output energy of 3 mJ was obtained. Making use of a LiF:F2-crystal as a saturable absorber, Q-switching operation was succeeded. There were three multiple-transverse-mode pulses with energy of 400 μJ and width of 11.5 ns for every individual pulse within per period. Some suggestions are presented here in order to obtain highly efficient single pulse with single-transverse-mode. |
