Analytic eigenmode solution for the self-filtering unstable resonator
An analytic solution for the bare cavity eigenmodes of a nonsymmetric self-filtering unstable resonator is obtained by a modal expansion in prolate functions, which is a complete and orthogonal set of eigenmodes for a symmetric confocal stable resonator.

Zusammenfassung: | An analytic solution for the bare cavity eigenmodes of a nonsymmetric self-filtering unstable resonator is obtained by a modal expansion in prolate functions, which is a complete and orthogonal set of eigenmodes for a symmetric confocal stable resonator. An accurate representation within the aperture is shown to require only three terms. An efficient use of Gaussian quadrature for the various calculations is described. |
