Abstract

The XeCl gain medium with its large spectral bandwith and high photon energy is an excellent candidate for amplification of ultrashort pulses to high power levels. High brightness subpicosecond XeCl laser sources1-3 have delivered peak optical powers of up to 1 TW. The bandwidth limited pulse duration for the XeCl gain medium is ~20G Is (Ref. 4) and can be fully exploited by combining nonlinear frequency doubling in BBO or KDP with standard femtosecond dye laser technology to generate UV seed pulses. For pulse durations approaching the bandwidth limit, however, gain suppression and pulse broadening can occur and result in devíatíons from standard puíse propagation theories such as the Frantz-Nodvik analysis. To gain understanding of the effect of limited bandwidth op ultrashort pulse amplification, we present here energy extraction measurements for a XeCI amplifier performed with 200-fs and 3-ps pulses.
