  • Abstract
    Diffusion-cooled and convective-cooled CW CO2 lasers have significantly different N2 partial pressure in their optimum laser gas mixture. While in diffusion-cooled lasers the N2 fractional concentration is normally within 20% of the total gas pressure, it ranges up to 60% in convective-cooled lasers. By considering various effects of N2 and solving a simplified rate-equation model analytically, the large difference in the optimum N 2 concentrations in these two types of CO2 laser is explained
