Abstract
Effects of mirror expansions to obtain higher power from an unstable resonator are proposed. Calculations are performed for expanding radius of a concave or a convex mirror to reduce the diffraction loss power from the concave mirror and to convert the power spread out from it into the output power. The Fresnel-Kirchhoff formula is used for the iterative computer calculation in the passive resonator and a CO2 laser. The calculations show that the increase of the output power can be obtained more than 25 percent with expanding the convex mirror in the CO2 laser.
