摘要

我们报告了飞秒激光脉冲在圆形锯齿膜和空间滤波器上孔径分离后的时空动力学的数值研究。研究发现，使用锯齿形膜片和空间滤波器可以显著降低衍射效应对脉冲时空动力学的负面影响。为了避免在随后的聚焦过程中辐射特性的显著畸变，制定了确定分离方案参数的准则。

Spatiotemporal Dynamics of Femtosecond Laser Pulses during Apodization by a Serrated Diaphragm

We report a numerical investigation of the spatiotemporal dynamics of a femtosecond laser pulse after aperture separation on a circular serrated diaphragm and a spatial filter. It is found that the use of serrated diaphragms together with a spatial filter can markedly reduce the negative impact of diffraction effects on the spatiotemporal dynamics of the pulse. Criteria are formulated to determine the parameters of the separation scheme in order to avoid significant distortions of the radiation properties during subsequent focusing.
