Paper Abstract

An output power of 2 kW is attained with a compact coaxial slow-flow CO2 laser. The resonator consists of two toric copper mirrors, which are tilted a small amount. These mirrors form an unstable resonator in azimuthal direction, from which two laser beams are extracted with high efficiency through a coupling aperture in one of the mirrors. The beam divergence of a single beam is nearly diffraction limited in the radial and azimuthal direction.
