An open resonator with toroidal mirrors
Abstract
The characteristics of a two-mirror, axially symmetric open resonator with a central aperture which is large in comparison with the wavelength are examined. The free vibration of the device is analyzed in the quasi-optical approximation, and an algorithm for approximating the field of natural vibration is described. The dependence of the resonator characteristics on various geometric parameters is investigated. It is shown that the structure of the field of natural vibration is determined by a parameter p, the ratio of the square of the radius of the torus circle to the product of the wavelength and the maximum distance between the mirrors. The radiation patterns of the basic mode from the coupling opening are calculated.
