Abstract: Main processes involved in the laser-target coupling are described,including the absorption of laser light,heat conduction of electron,plasma motion,nonequilibrium ionization,laser X-ray conversion and the radiation transport.It outlines the numerical simulation,presenting the partial differential equations,constructing the finite difference schemes and describing the solving methods.Finally,some calculated results are given.

Key words: inertial confinement fusion, laser-target coupling, numerical simulation
