Paper Abstract

The problem of interaction of short laser pulse (light frequency (omega) o, pulse duration (tau) < 1s/VTi, 1s is the skin depth, VTi is the ion velocity) with dense ((omega) o << (omega) pe) semi-infinite plasma was solved. We formulated the self- consistent problem of obtaining the electron distribution function and space dependence of the electric field in the skin layer, and solved the problem for several cases analytically and numerically. On the basis of the obtained solution, we have calculated mean electron energy, absorption coefficient, Bremsstrahlung radiation, and time-dependent skin depth. We have also found dependence of the absorption coefficient on the wave incidence angle and its polarization.
