为了获得高功率高重频窄脉宽激光输出, 通过双棒串接技术和高重频电光腔倒空技术,实现了百瓦级短脉宽、高重频和高稳定1 064 nm线偏振激光输出。在电源输入电流35 A, 在不加调Q时候, 获得高达426瓦连续线偏振激光输出, 电光转化效率18.8%。在加调Q时, 驱动频率10 kHz的条件下, 获得最高功率240 W线偏振1 064 nm激光输出, 单脉冲能量24 mJ, 脉宽5 ns左右, 峰值功率约4.8 MW。试验结果表明: 通过腔倒空调Q技术和双棒串接技术, 可以实现高功率高重频窄脉宽线偏振1 064 nm激光输出。

To acquire high power, high repetition and narrow width laser, hundred Watts narrow width, high repetition, and high stability polarized 1 064 nm laser output is acquired by two laser heads in tandem technology and cavity-dumped technology. When the input current is 35 A and electro-optically Q-switch is absent, 1 064 nm polarized laser output power of 426 W is acquired with a conversion of 18.8 % from electricity to light., 1 064 nm polarized laser output power of 240 W is acquired with electro-optically Q-switched repetition of 10 kHz, single pulse energy is 24 mJ with pulse width 5 ns, and peak power 4.8 MW. It is experimentally indicated that Cavity-dumped Q-switched technology and two laser heads in tandem technology can be used for high power, high repetition, narrow width and polarized laser output.
