Abstract

The picosecond laser pulse interaction with different targets was studied on the NEODIM installation. THE processes in laser-produced plasma were considered theoretically and by numerical calculations by RAPID-SP and RADIAN codes with taking into account the pre-pulse with energy contrast of the factor 10³-10⁴. Interpretation of the experiments, estimations and numerical results for plasma and electromagnetic fields parameters, fast electron and (gamma) -radiation are presented in this work.
