Paper Abstract

A focusing combination scheme based on four incident plane waves with a caliber of 290mm is investigated to enhance the peak power of the shooting laser in the ICF fast ignition. Calculated and simulated results indicate that about 67% energy is focused in the center spot using an optimized paraboloidal mirror, and the light peak intensity is enhanced about 13.95x1010 times. Besides, the tolerances of the light spot position and the initial phases are analyzed in detail for experiment.
