Abstract
We report on a joule-level, 1047 nm Nd:YLF master oscillator power amplifier laser with near-diffraction-limited beam quality. The master oscillator and two-stage two-pass amplifier were all-flashlamp-pumped. The laser produced 2 J output pulses with 3 ns duration at 10 Hz pulse repetition rate. High beam quality was achieved by using a liquid stimulated Brillouin scattering mirror and additional astigmatism compensation.
摘要
我们报道了一种焦耳级、1047纳米的钕：钇锂氟化物主振荡器功率放大器激光器，其光束质量接近衍射极限。主振荡器和两级双程放大器均由闪光灯泵浦。该激光器在10赫兹脉冲重复频率下产生了持续时间为3纳秒的2焦耳输出脉冲。通过使用液体受激布里渊散射镜和额外的像散补偿实现了高光束质量。
