Abstract
The interaction of differently polarised femtosecond laser pulses with an i ntensity of 10(15) - 10(17) W cm(-2) with the surface of a solid target was calculated theoretically. In the calculation of absorption of the laser ra diation, the electrodynamic, hydrodynamic, and kinetic equations were solve d in combination at the plasma-vacuum boundary. The dependences of plasma r eflectivity on the intensity, polarisation, and the angle of incidence of l aser radiation on the target were determined. A comparison with experimenta l data was made.
