摘要
The laser discharge space is limited by closely adjacent walls so that it acts for the radiation built-up in it as a waveguide with two equidistant waveguide surfaces. Their dimension perpendicular to the beam direction is large in comparison with their spacing. Resonator boundaries in the beam direction consist either of plane mirrors directly at the discharge space, or of curved concave mirrors at a distance from the discharging space. The waveguide surfaces are lateral surfaces of two concentric cylinders. The laser gas is excited by the hf electromagnetic fields coupled into the waveguide space.
