LD side-pumped Nd∶GdVO4 532 nm green laser

  • 摘要: 为了获得高功率窄脉宽532 nm绿光激光输出,通过高重复频率声光驱动调Q技术和LD侧面泵浦Nd∶GdVO4技术,获得高功率线偏振1 064 nm激光输出。采用内腔倍频方式,对非线性晶体KTP进行频率变换,实现高功率窄脉宽绿光激光输出。在电源输入电流30 A,调Q驱动频率10 kHz的条件下,获得最高功率30 W线偏振1 064 nm激光输出,脉宽30 ns,倍频KTP晶体获得23.4 W的532 nm绿光输出,1 064 nm到532 nm转化效率为78%。实验结果表明:通过声光调Q技术和LD侧面泵浦Nd∶GdVO4技术,可以实现高功率线偏振窄脉宽1 064 nm激光输出,倍频非线性晶体KTP可获得高功率窄脉宽532 nm激光。
    Abstract: To acquire high-power narrow-width 532 nm green laser,we used the acousto-optic driving Q-switched synchronization technology with high repetition rate and the laser diode (LD) side-pumped Nd∶GdVO4 laser to get high-power linearly polarized 1 064 nm laser output. We achieved high-power green laser output by intra-cavity frequency doubling and KTP non-linear frequency conversion. As the input current was 30 A and the Q-switched frequency was 10 kHz, we got the 1 064 nm polarized laser output with maximum power of 30 W and narrow width of 30 ns, and the 532 nm green laser output from KTP crystal with the maximum power of 23.4 W. Conversion efficiency of 1 064 nm to 532 nm was 78%. Experiment results indicate that the acousto-optic Q-switched technology and LD side-pumped Nd∶GdVO4 laser in tandem technology can be used to obtain high repetition frequency 1064nm polarized laser, and the high-power 532 nm green laser can be output by KTP non-linear frequency conversion.
