Abstract

A technique for selecting a single high-order lateral mode of a rf excited slab waveguide laser is described. An in-cavity grid which matches the periodicity of the desired mode, together with slab waveguide dimensions which create coherent imaging by the Talbot effect, have produced a stable output power of 155 W in a high spectral purity, single-resonator mode.
