Abstract

A terawatt-class laser, based on the amplification of subpicosecond pulses in XeCl discharge amplifiers, is described. The system generates 250-mJ, 335-fsec pulses at a sustained 1-Hz repetition rate. Using f/3.7 optics, focal-spot dimensions of 3.4 μm × 4.1 μm are measured for the fully amplified output beam, thus demonstrating a mean focal-volume intensity of 4.6 × 10¹⁸ W/cm². With f/1 optics, this system is therefore capable of producing a focused intensity of 6.4 × 10¹⁹ W/cm².
