摘要我们报道了日本国立量子科学技术研究所关西光子科学研究所安装在J-KAREN-P激光器上的等离子体镜系统的设计和表征。单等离子体镜系统的反射率超过80%。此外，时间对比度提高了两个数量级，在1 ps前的主脉冲。此外，在等离子体镜能量密度小于100 kJ/cm 2时，等离子体镜后的激光近场空间分布保持恒定。我们还研究了在有无等离子体镜系统的情况下，脉冲能量、脉宽和指向稳定性的差异和起伏。
Abstract We report on the design and characterization of the plasma mirror system installed on the J-KAREN-P laser at the Kansai Photon Science Institute, National Institutes for Quantum Science and Technology. The reflectivity of the single plasma mirror system exceeded 80%. In addition, the temporal contrast was improved by two orders of magnitude at 1 ps before the main pulse. Furthermore, the laser near-field spatial distribution after the plasma mirror was kept constant at plasma mirror fluence of less than 100 kJ/cm2. We also present the results of investigating the difference and the fluctuation in energy, pulse width and pointing stability with and without the plasma mirror system.
