Abstract

The spatiotemporal coupling (STC) distortion of large aperture ultra-high peak power laser will stretch the focused pulse and reduce the peak power. In order to accurately characterize the laser field distribution and compensate the spatiotemporal coupling distortion, a single-frame measurement of full three-dimensional STC distortion based on carrier frequency distinguished spectral interferometry (CFDSI) is proposed. The setup requires only a slit array attached in front of an imaging spectrometer. The whole process of CFDSI is simulated in this study, and the simulation results prove its correctness and effectiveness.
