| 内容記述 | We report on a detailed analysis of the influence of the random spectral phase noise on temporal contrast of an ultra-high intensity laser pulse. We accurately evaluate the impact of stretcher and compressor optics on the contrast pedestal of the ultra-high intensity laser pulse by precise quantitative characterization of the optics surface. The surface roughness of tens of nanometers on the stretcher and compressor optics causes random spectral phase noise, which reduce the temporal coherence of the main pulse and generates a noisy structure around the main pulse. A degradation of a few orders of magnitude is estimated with the random spectral phase noise. | |||||
