Paper Abstract

The properties of output beams for slab CO2 lasers of output power in the range from few tens of watts up to 1 kW with waveguide-unstable cavities have been studied both theoretically and experimentally. It is shown that such lasers provide close to single-mode operation, smoothing-out one-peak profile and near-diffraction-limited beams at high specific output power. New slab cavity scheme with phase shifting array mirror has been proposed and developed. A highly spatially suppressed and highly bright output beam was obtained.
