Abstract
A pair of XeCl gain modules was used to amplify 350-fsec 308-nm pulses to ~10-mJ energies with <1-mJ amplified-stimulated-emission content. Gentle focusing in air of the ~1.5-mJ beam from the first amplifier alone produces ~1000-cm−1 broadening of the pulse spectrum by the mechanism of self-phase modulation.
