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.
