Study on the mechanism of the fast ignition in laser fusion

The mechanism of the fast ignition in laser fusion and ultra-intense and ul tra \ \ shea-pulse laser plasma interaction are analysed theoretically and simulated numerically. Two-and Two and half-dimensional cloud-in-cell simul ation codes are developed and simulation results for ultra-intense and ultr a-shea-pulse laser propagating in an inhomogeneous plasma and the boring ve locity and the depth of the hole are presented,as well as the parameter ind ex of the laser device of fast ignition in laser fusion.
