Abstract

A 10-kW CO₂ laser has been developed with design emphasis on the output beam quality. The laser is of a fast transverse-flow type, wherein the discharge takes place along the gas flow. Both stable and unstable resonators were used and compared in their output and beam properties. Results show that diffraction inside the unstable resonators plays an important role in determining their beam characteristics. Near diffraction limited beams have been obtained from the unstable resonators.
