摘要

理论阐述了光谱色散匀滑(SSD)技术的物理内涵,即SSD的焦斑匀滑效果来源于远场基元电场相位随时间的演化,在实际应用中不存在“运动”焦斑的物理图像。在此基础上,建立了远场强度分布形式不变但空间位置随时间变化的“强度扫动”光束的理论模型,通过数值模拟研究其匀滑特性,并与SSD的匀滑效果进行了对比分析。

Abstract

The physical content of smoothing by spectral dispersion (SSD) technology is theoretically explained that the focal spot smoothing effect of SSD results from the temporal change of the far-field primitive electric field phase, and there is no physical image of "moving" focal spot in the practical application of SSD. On this basis, the theoretical model of "intensity sweep" laser beam, which has a far-field intensity distribution with constant form but temporal changed spatial position, is established. The smoothing characteristics of the beam are studied by numerical simulation compared with that of SSD.
