我们报告了 J-KAREN-P 激光器在 0.1 Hz 下产生了 63 J 的宽带脉冲能量，该激光器基于 OPCPA/Ti：蓝宝石混合架构。脉冲压缩低至 30 fs 表示峰值功率超过 1 PW。主脉冲之前的高时间对比度已在 10 J 输出能量下得到证实。通过使用 f /1.3 离轴抛物面镜聚焦 0.3 PW 激光，可以在目标上实现 10(22) W/cm(2) 的高强度。强度超过 10(22) W/cm(2) 的激光物质相互作用的基本过程属于一个新的科学分支，这将是我们基础设施的主要研究任务。 (c) 2018 美国光学学会
We report the generation of 63 J of broadband pulse energies at 0.1 Hz from the J-KAREN-P laser, which is based on an OPCPA/Ti: sapphire hybrid architecture. Pulse compression down to 30 fs indicates a peak power of over 1 PW. High temporal contrast of 10(12) prior to the main pulse has been demonstrated with 10 J output energy. High intensities of 10(22) W/cm(2) on target by focusing a 0.3 PW laser with an f /1.3 off-axis parabolic mirror have been achieved. Fundamental processes of laser matter interaction at over 10(22) W/cm(2) intensities belong to a new branch of science that will be the principal research task of our infrastructure.
