We demonstrate high-energy pulse compression by stimulated Brillouin scattering (SBS) in water using an energy-scalable generator amplifier setup. Pulse compression from 2.4 J, 12 ns at 532 nm to 1.2 J, 300 ps has been achieved, which to our knowledge represents the highest compressed energy achieved at 532 nm using SBS and is only limited by the size of our optics. Our setup is robust and stable over long periods of operation (2% of energy fluctuation and <3% shot-to-shot variation of pulse width).
我们使用能量可扩展的发生器放大器装置，通过水中的受激布里渊散射（SBS）实现了高能脉冲压缩。已实现从532纳米处的2.4焦耳、12纳秒脉冲压缩至1.2焦耳、300皮秒，据我们所知，这代表了使用SBS在532纳米处实现的最高压缩能量，且仅受我们光学元件尺寸的限制。我们的装置在长时间运行中坚固且稳定（能量波动2%，脉冲宽度逐次变化<3%）。
