| 摘 要： | 采用峰值功率为500 W准连续激光二极管(LD)阵列侧面泵浦Nd:YAG晶体,Cr4+:YAG可饱和吸收体作为被动调Q元件,在重复频率为40 Hz时实现了单脉冲能量为8.24 mJ、脉冲宽度约7 ns的1 064 nm TEM00模调Q激光脉冲输出,脉冲峰值功率达到1.2 MW,从而为主振荡功率放大(MOPA)系统提供高峰值功率、高光束质量的种子源。对泵浦功率和泵浦脉冲宽度对输出脉冲特性的影响进行了实验研究。

| Abstract: | A passively Q-switched singlemode quasi-diode-pumped Nd:YAG laser that uses Cr4+:YAG as a saturable absorber is demonstrated.The single pulse energy of 8.24 mJ and the pulse width of 7 ns are obtained at the repetition of 40 Hz.The peak power of the pulse reaches to 1.2 MW.It can be used as a high-peak power injection seeded laser with high-beam quality for MOPA system.The effects of the pump power and the pump width on the output pulse characteristics are experimentally studied. |
