| Abstract: | This paper investigates the coupling of5?102W/cm2 peak intensity to aluminum target,original in vaccum. The interaction of plasma with laser radiation is discussed emphatically,which is described by the one-dimension, one-fluid, two-temperature radiation hydrodynamics model. The numerical simulation model of the interaction of mental target with laser radiation is set up. The calculation results show to be in good agreement comparing with other references. |
