Abstract

A theoretical calculation of the principal parameter in an open coaxial cavity resonator formed by a barrel-shaped outer mirror and a cylindrical inner mirror was carried out. Analytic expressions were derived for the natural frequencies, the positions of the caustics, the field distributions and the ratios of the values of Q for various oscillation mode for 2πd/λ ≫ 1 (λ is the wavelength; d is the characteristic dimension of the cavity). The results of numerical calculations allow the geometry of the cavity to be chosen for practical application.
