Abstract
In order to reduce the costs of industrial C02 lasers in the 1 kW range, diffusion cooling of the laser gas instead of convectional cooling by fast gas flow is investigated. The power output per unit discharge length for conventional slow-flow C02 lasers with cylindrical discharge tubes is limited to less than 100 W/m. Rf-excitation of the laser gas permits the use of large-area planar or annular (coaxial) discharges, leading to power extraction capabilities up to 20 kW/qm discharge area. Specially coaxial discharge structures are simple low-cost devices.
