Abstract
An integrated thermal and hybrid model is present in this paper to study the relative physical characteristics when target is irradiated by high-intensity laser beam. The model can describe the thermophysical effect in the initial stage for plasma formation and the following process for plasma expansion. Take silicon target as an example, the numerical solutions are obtained from the integrated model using a finite difference method. The results from the present model indicate that the plasma dynamic expansion behavior can be evidently influenced by the vaporization and surface temperature of ablated material. Their effects are similar to a dynamic source for plasma expansion and increase the expansion acceleration. The expansion characteristics from our results are found to be consisting with the relative studies.
