Abstract
It is proposed to calculate (in the diffraction approximation) fields in optical cavities with shaded axial zone and large mirror aperture, in a cylindrical coordinate frame, using a new algorithm based on the use of the stationaryphase method. Unlike the already known ones, the method has high efficiency in the region of large Fresnel numbers, and is close in speed to the method of fast Fourier transformation. The procedure is described and specific calculation results that illustrate the proposed method are presented.
