摘要
光谱色散匀滑(SSD)技术已经广泛应用于国内外各大高功率激光驱动器。但是由于工程设计原因，美国国家点火装置(NIF)以及国内神光-III原型(TIL)装置都只采用了一块光栅，相较于传统SSD技术，焦斑匀滑效果有所不同。经模拟发现，在初始的100 ps以内，缺失色散光栅的SSD技术匀滑性能下降，可以通过优化调制频率来降低这种影响。通过对单光栅下的SSD技术分析研究，为SSD技术在大型激光装置上的优化应用提供理论基础。
Abstract
Smoothing by spectral dispersion (SSD) technology has been widely used for many high-power laser drivers. However, due to the engineering design reasons, national ignition facility (NIF) and technical integration experiment line (TIL) use only one grating. It will affect the smoothing efficiency, especially at the beginning time. But we can reduce it by the way of optimizing the modulation frequency. Finally we analyse the SSD technology with one grating and provide a theoretical basis for the optimization of high-power laser drivers.
