Title: Amplification of subpico second UV pulses in the multistage GARPUN-MTW Ti:sapphire - KrF laser system

Abstract

Terawatt 248-nm UV pulses with an energy of 0.62 J, a width of no more than 1ps, and a divergence of 20 {mu}rad have been obtained in the first experiments on the GARPUN-MTW Ti:sapphire - KrF laser system at double-pass amplification of frequency-tripled pulses from the Ti:sapphire front end in wide-aperture electron-beam-pumped KrF amplifiers. The contrast of short pulses relative to the amplified spontaneous emission is found to be {approx}10{sup 6} for energy densities and {approx}10{sup 11} for intensities. The specificity of short-pulse amplification in an active medium with fast population inversion recovery and advantages of amplification of trains of short pulses or short and long pulses are discussed. The peak power of single subpicosecond pulses in this laser system can be increased to 30TW, and the focused beam intensity can be as high as 10{sup 20} W cm{sup -2}. (lasers)
