摘要：
The interaction of differently polarised femtosecond laser pulses with an intensity 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 radiation, the electrodynamic, hydrodynamic, and kinetic equations were solved in combination at the plasma-vacuum boundary. The dependences of plasma reflectivity on the intensity, polarisation, and the angle of incidence of laser radiation on the target were determined. A comparison with experimental data was made.
