Paper Abstract

Sealed-off slab CO2 lasers excited by a dielectric barrier discharge are studied. The laser output power is measured at excitation frequencies between 0.4 and 0.6 MHz; discharge gaps are in the range 1.6 Ñ 6.0 mm. Due to the scaling laws of radio frequency excitation no laser activity should be possible for the laser under investigation. The use of high-frequency excitation (0.4 - 0.6 MHz) combined with a dielectric barrier discharge gives the possibility of creating a homogeneous and stable CO2 laser gas discharge with high laser activity. The excitation efficiency of the all-solid-state generator reaches 90%.
