Abstract

This paper investigates the high pressure operation of a device which combines slab laser type design, with slab discharge dimensions of 200×50×5mm, with fast axial flow gas cooling. The laser offers the possibility of materials processing over a wide range of optical intensities and PRFs, including continuous operation. In continuous mode, the laser has successfully operated at intracavity pressures of up to 500 Torr. Preliminary pulsing studies at an intracavity pressure of 500 Torr give minimum allowed pulse durations of 30 µs with peak pulse powers of greater than 1 kW from a single discharge section.
