We report on a multi-petawatt 3-cascaded all-optical parametric chirped-pulse amplification laser facility. The experimental results demonstrate that the maximum energy after the final amplifier and after the compressor is 168.7 J and 91.1 J, respectively. The pulse width (FWHM) is 18.6 fs in full width at half maximum after optimization of pulse compression. Therefore, 4.9 PW peak power has been achieved for the laser facility. To the best of our knowledge, this is the highest peak power reported so far for an all-optical parametric chirped-pulse amplification facility, and a compressed pulse shorter than 20 fs is achieved in a PW-class laser facility for the first time.
我们报道了一种多拍瓦级的三级全光参量啁啾脉冲放大激光装置。实验结果表明，最终放大器之后和压缩器之后的最大能量分别为168.7焦耳和91.1焦耳。经过脉冲压缩优化后，脉冲宽度（半高全宽）为18.6飞秒。因此，该激光装置实现了4.9拍瓦的峰值功率。据我们所知，这是迄今为止全光参量啁啾脉冲放大装置所报道的最高峰值功率，并且在拍瓦级激光装置中首次实现了短于20飞秒的压缩脉冲。
