Dependences of density profile steepening parameters under action of pondermotive forces, as well as resonance and parametric absorption coefficints at incidence of s- and p-polarized electromagnetic wave onto flat plasma layer are obtained on the basis of numerical solution of the set of contracted Maxwell equations combined with isothermal quasi-static plasma flow equat ions. The model of absorption of laser radiation by spherical target is formulated, allowing to compute back-bremsstrahlung, resonance, and parametric absorption taking into account refraction of laser radiation in the corona, density profile steepening, and Mandelstam-Bri1louin forced scattering. One-group fast-electron energy transfer equation is proved.
