Abstract

In this paper, we present a theoretical model which treats one-dimensional target heating and vaporization as well as energy absorption and collision reactions in the melting metal vapor. The coupling effects have been calculated for 0.308-micrometers XeCl laser radiation to aluminum. The incident laser intensity and the pulsed duration are 10⁷ - 10⁹ W/cm² and 80-ns respectively. The time relations of thermal and impulse coupling coefficients are obtained by solving non-linear heat conduction and rate equations about the temperature and density. These results are compared with the experiment measurements and the agreement is fairly good.
