Paper Abstract

An approximate solution of the problem of the misalignment sensitivity in hollow waveguide resonator with Gaussian reflectivity mirror is presented. With the help of ABCD matrix laws an approximate expression which relate the coupling losses to the distance between end mirror and waveguide aperture, radius of mirror curvature, Gaussian mirror parameter and output mirror tilt angle is derived. Characteristics revealing the effects of resonator parameters on coupling losses are presented for various cavity configurations. It is shown, that using of Gaussian output mirror decreases resonator misalignment sensitivity.
