Abstract:
本文介绍了微型LD端面泵浦的窄脉冲Nd:YLF激光器。采用透过率为70%的Cr:YAG晶体作为被动调Q晶体，在泵浦功率为5 W，1.33 kHz的重复频率下，得到脉冲能量150 μJ的1047 nm基频光输出，再通过LBO腔外倍频，最终实现脉宽为2 ns，脉冲能量为67.7 μJ的523.5 nm脉冲激光输出。
This paper introduces a miniature LD end-pumped narrow pulse Nd:YLF laser. Using Cr:YAG crystal with 70% transmittance as passive Q-switched crystal, the pulse energy of 150 is obtained at the repetition frequency of 1.33 kHz with a pump power of 5 W μ J’s 1047 nm fundamental frequency light output, and then through LBO external frequency doubling, the final pulse width is 2 ns, and the pulse energy is 67.7 μ J’s 523.5 nm pulsed laser output has the advantages of high beam quality, high peak power, high repetition rate, narrow pulse, simple and compact.
