Characterizing spatio-temporal aspects of chirped pulse amplification laser micro-cone target interaction

A numerical study of spatio-temporal distortions effect on the output chirped pulse amplification (CPA) laser beam at the interaction with a micro-cone target was developed. For this, several laser configurations based on CPA technique have been designed and complex study for spatio-temporal distort...

Description
Summary:A numerical study of spatio-temporal distortions effect on the output chirped pulse amplification (CPA) laser beam at the interaction with a micro-cone target was developed. For this, several laser configurations based on CPA technique have been designed and complex study for spatio-temporal distortions compensation has been elaborated using a raytracing model from Optica module of Mathematica in order to determine the optimum conditions to streamline the laser field intensification in the vicinity of laser–conical target interaction point. This numerical model offers an effective solution to fine tune the output CPA beam pulse duration or to control or mitigate the current beam pointing fluctuations caused by specific internal processes during experiments in high-power regimes.
