High-power diffusion cooling planar waveguide $CO_2$ laser

Özet

A diffusion-cooled $CO_2$ laser using a coaxial waveguide is investigated theoretically. The resonator extracting the laser beam consits of two annular plane mirrors enclosing the two ends of the waveguide. A theoretical resonator model based on the vector modes of propagation in a dielectric coaxial waveguide is described.
