Paper Abstract

The activation of a full scale single beam prototype of a multipass amplifier cavity based fusion class laser has been completed. A 35 multiplied by 35 cm2 beam is amplified during four passes through an 11 slab long amplifier in a cavity, and is switched out using a full aperture Pockels cell and polarizer. Further amplification is achieved in a five slab long booster amplifier, before being frequency tripled by a Type I/Type II frequency converter. We present initial performance results of this laser system, called Beamlet. At 1 omega, energies up to 17.3 kJ have been generated in a 10 ns pulse, and frequency tripled beams up to 8.3 kJ in a 3 ns pulse.
