Abstract

Time-resolved gas dissociation inside diffusion-cooled RF excited CO2 lasers was measured with NIR laser absorption spectroscopy and UV-VIS emission spectroscopy. Roto-vibrational temperatures were derived directly in the discharge region. Effects of gas additives on the plasma processes were studied.
