Four different schemes for the generation of femtosecond input pulses for ArF amplifiers are described. Pulseenergies of 100 nJ were obtained with phase-matched frequency mixing of a Raman-shifted frequency-doubledpulse derived from a 537-nm femtosecond dye-laser pulse. Excellent spatial, spectral, and amplitude stability wasobtained when a broadband, nanosecond dye laser at 690 nm was used as a Raman seed pulse. Preliminaryamplification experiments resulted in 0.5-mJ ArF output pulses of 340 fsec.
