Abstract: By analyzing the spherical-harmonic modes of irradiation nonuniformity, the general conditions are acquired for perfectly uniform irradiation of spherical targets for direct driven laser fusion from a finite number of laser beams. The results provide the theory for optimum designing practical multibeam irradiation systems and evaluating irradiation nonuniformity of spherical targets. Some typical examples that satisfy the conditions are presented.
