Paper Abstract

Results of numerical model operation of an X-rays spectra of radiation of the laser plasma received on an aluminium target are presented. They have shown oscillation of an X-rays in a spectral range 1 - 10 keV with intensity up to Irent = 1011W/cm2. In calculations the mathematical model including combined equations of ideal magnetohydrodynamics in view of transport of laser radiation and a self-radiation of laser plasma, supplemented by equations of state and absorption constants, the given in a tabulared view was used. It has been found that the account of a heating of plasma by laser radiation sharply changes morphology of a powerful shock wave of plasma. Calculation has shown that near to a surface of a target there is an oscillation of spontaneous magnetic fields with an induction about 5 x 107 Gs. Besides velocity of a motion of front of laser plasma is observationally estimated at an optical breakdown in atmosphere which has made quantity about 7.5 x l06cm/s.
