在这项工作中，我们报告的成功实施等离子体镜（PM）技术的LFEX激光设备在激光工程研究所，大坂大学。LFEX激光脉冲通过球形等离子体镜成功地重新聚焦在靶室中心（TCC），产生5× 10 18 W cm− 2激光强度，在PM上的激光通量约为90 J cm− 2时具有45%的反射率。实验结果表明，PM重聚焦后的LFEX脉冲的稳定聚焦和指向。对比度的提高通过较冷的快电子斜率温度分布以及通过发射亚微米塑料箔的能力来证明，从而获得最大能量超过20 MeV的质子束。实验结果定性再现的二维粒子在细胞模拟。
In this work we report the successful implementation of plasma mirror (PM) technology on an LFEX laser facility at the Institute of Laser Engineering, Osaka University. The LFEX laser pulse was successfully refocused at the target chamber center (TCC) by means of a spherical plasma mirror, resulting in 5× 10 18 W cm− 2 laser intensity, with 45% reflectivity at a laser flux of about 90 J cm− 2 on the PM. Experimental results show stable focusing and pointing of the LFEX pulse after PM refocusing. The contrast improvement was demonstrated by both cooler fast electron slope temperature distribution as well as by the ability to shoot sub-µm plastic foils obtaining proton beams with maximum energy exceeding 20 MeV. Experimental results are qualitatively reproduced by 2D particle in cell simulations.
