Paper Abstract

We studied the spatial beam profile of a high peak power, ultra-short laser pulse passing through a diffractive beam shaping system. In theoretical simulation, we considered the effects of both group velocity dispersion and nonlinear self-phase modulation on the reshaped beam profile. The output spatial and temporal intensity profile of a 100-fs laser pulse at different energy levels is calculated. We also present the experimental result of the fluence profile at the beam shaping system's target plane for a 1-mJ, 100-fs near infrared laser pulse which is generated from a multi-pass laser amplification system.
