| 摘 要： | 在神光II九路装置上,利用谱色散匀滑(SSD)技术结合分布式相位板(DPP)技术,研究了激光焦斑在一维、二维谱色散匀滑下的分布。结果表明,一维谱色散匀滑使焦斑的焦斑通量对比度由0.7634均方根(RMS)]下降到0.3685(RMS),结合二维匀滑下降到0.2638(RMS);并结合各种评价方法对焦斑进行分析。实验为谱色散匀滑技术在神光II在线应用提供了参考。

| Abstract: | Two-dimensional performance of uniform irradiation with the smoothing by spectral dispersion(SSD) and distributed phase plates(DPP) is researched on the SG II laser facility.The results of experiments in free space show that 1D-SSD makes the root mean square(RMS) focus drop to 0.3685 from 0.7634(without SSD),and 2D-SSD supplied RMS is 0.2638.Other appraising methods of focus verify the conclusion.This experiment is especially meaningful for on-line 2D-SSD experiment. |
