Abstract

Radiation characteristics of planar diffusion-cooled CO₂- and CO-lasers created using the same design and excited by a RF discharge at a frequency of 40 MHz have been studied. A single-mode cw lasing power of ~ 100 W has been achieved with an efficiency of ~ 10 % for a CO₂-laser with a diffraction-limited radiation divergence of 4 - 7 mrad. For a CO-laser with electrode temperature of -65 °C, a cw output power of 60 W with an efficiency of ~ 10% has been achieved in the wavelength range 5.3 - 6.0 μm.
