Аннотация:Very intense interfering beams generated a high-temperature surface femtosecond plasma with periodically modulated parameters. The dynamics of the efficiency of diffraction by such an induced ’grating’ was studied A background-free method for measuring the duration of very intense laser pulses on the basis of noncollinear second-harmonic generation was demonstrated An increase in the second-harmonic signal was observed for the first time under the conditions of resonant excitation of a surface electromagnetic wave by very intense radiation of femtosecond duration.
