The optical parametric-chirped pulse amplification (OPCPA) based on large-aperture nonlinear optical crystals is promising for implementation of an ultrahigh peak-power laser system of 10 PW and beyond. We demonstrated the highest energy broadband OPCPA at 800 nm, to the best of our knowledge, by using an 80 mm in diameter LiB(3)O(5)(LBO) amplifier, with an output energy of 28.68 J, a bandwidth of 80 nm (FWHM), and conversion efficiency of 25.38%. After compression, a peak power of 0.61 PW with 33.8 fs pulse duration is produced.
基于大口径非线性光学晶体的光参量啁啾脉冲放大（OPCPA）有望实现 10PW 及以上超高峰值功率激光系统。我们使用直径为 80mm 的 LiB(3)O(5)(LBO) 放大器，实现了迄今为止最高能量的宽带 OPCPA，输出能量为 28.68J，带宽为 80nm（FWHM），转换效率为 25.38%。经过压缩后，产生了峰值功率为 0.61PW、脉宽为 33.8fs 的脉冲。
