Paper Abstract

Focusing conditions of the cw CO2 laser radiation beam emitted from the stable semi- spherical resonator have been investigated theoretically and experimentally. The laser beam behavior with the distance to the resonator output has been analyzed for two cases of the beam output coupling; through the flat and through the concave-convex partial reflector. The latter forms a meniscus lens of a long focal length. The meniscus outcoupler reduces divergence of the beam leaving the resonator and also allows for higher beam diameter in the plane of the focusing lens. It results in the smaller dimensions of the focus spot and in the higher values of the radiation power density which are required for some applications.
