| Abstract: | Transform limited pulses of 200–250 fs duration at 308 ns generated by a specially designed excimer laser pumped dye laser system have been amplified in a XeCl gain module. Simultaneous study of the spectrum and the temporal behaviour of the amplified UV pulses showed bandwidth limitation by the gain spectrum of XeCl. This effect is strongly dependent on the operational condition of the amplifier; in a single pass amplification scheme 0.5 mJ, 250 fs pulses, in a double pass arrangement 5 mJ, 220 fs pulses were obtained, with excellent reproducibility. |
