Abstract

We report a theoretical study of the integration between UV laser pulse and the plasma expanding in front of the target. For description of the laser-plasma interaction process we used the gasdynamic approach. The plasma is assumed to be an electrically neutral gas, which contains neutral atoms, ions, and electrons in Local Thermodynamic Equilibrium (LTE). For study this interaction we used an Coupled Euler Lagrange numerical code. In addition it was possible to investigate the mechanism of plasma absorptivity and also calculating the laser energy which is effectively transmitted to the target.
