Mathematical Models and Computer Simulations Aims and scope

Abstract

We consider the results of computational experiments concerning the expansion of a plasma generated by laser radiation at the stage of a nanosecond prepulse ahead of the main femtosecond-range pulse. A series of plasmodynamic calculations are performed for various laser target materials. It is shown that in the considered problem statement, which corresponds to the typical conditions of full-scale experiments, the distribution of the laser plasma density as a whole is satisfactorily approximated by a simple three-parameter formula.
