摘要：

A one-dimensional bulk absorption model to simulate the accelerating process of laser-driven flyer plate is presented, in which the laser energy deposition, the laser absorption in plasma and acceleration of flyer plates are included. In the laser intensity range of GW/cm2, the gasdynamical behavior of the ablated foil plasma is described with a modified one-dimensional Lagrangian hydrodynamic code. The histories of the flyer velocity and the density profiles are given by this model. The calculated results of the ablated thickness of films in the launch of laser-driven flyer plates are in good agreement with the experimental results.
