High-intensity subpicosecond XeCl laser system
- Los Alamos National Laboratory, Los Alamos, New Mexico 87545 (US)
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 {ital f}/3.7 optics, focal-spot dimensions of 3.4 {mu}m {times} 4.1 {mu}m are measured for the fully amplified output beam, thus demonstrating a mean focal-volume intensity of 4.6 {times} 10{sup 18} W/cm{sup 2}. With {ital f}/1 optics, this system is therefore capable of producing a focused intensity of 6.4 {times} 10{sup 19} W/cm{sup 2}.
