The Analysis of the Non-paraxial Effects of the Ultrashort Pulsed Beam in Free Space
自由空间中超短脉冲光束的非傍轴效应分析

Based on the spatial and temporal Fourier Transform, we developed a non paraxial correction method to the ultrashort few cycle pulsed beam, and it was illustrated with the family of pulsed Gaussian beam. The examples shows that, because of the exist of the spatiotemporal coupling, the temporal distribution of the pulse would influence the spatial distribution of the non paraxial correction.
