Simulations and Measurements for Signatures of Spatio-Temporal Couplings in Laser Fields

Abstract

The propagation behaviour of spatio-temporal couplings in ultra-short lasers was simulated using an in-house, mesh-free, 4D Gaussian decomposition propagation code. An expository example is the generation of spatial chirp in the focus of a laser with initial angular dispersion, affecting the laser experiments. Simulations were supported by laboratory measurements.
