CALCULATION OF LASER SPOT PARAMETERS ON WALL OF CYLINDRICAL HOHLRAUM FOR LASER INDIRECT DRIVEN FUSION

The parameters of the laser on the wall of a cylindrical hohlraum and at the laser entrance holes have been calculated using geometry optics, including the position,shape and side of laser spots, as well as the intensity distribution inside the spots. The results are useful for analyzing the initial irradiation uniformity on the capsule and the irradiance on the wall of hohlraum and for effectively injecting laser into the hohlraum.
