Abstract: The excitation of plasma waves, the acceleratioin of electrons and the generation of suprathermal electrons in the processes of laser plasma resonant absorption have been simulated using the developed two dimensional multi time scale fully electromagnetic relativistic particle simulation computer code. The simulation results prove to be reasonable through theoretical analyses.

Key words: interaction of laser plasma, particle simulation of plasma, resonant absorption, suprathermal electrons, plasma waves, wavebreaking
