Modes of a thermoelastically disturbed resonator
O. N. Naĭda
Abstract:
A theoretical analysis is reported of an optical resonator in the form of a circular cylinder with fixed flat reflecting ends subjected to uniform heating. The modes of such a thermoelastically perturbed resonator are calculated in the first order of the perturbation theory using a small parameter describing the anisotropy of thermooptic perturbations. Explicit expressions are obtained (in terms of the Laguerre polynomials) for the perturbed wave functions, particularly for the distorted TEM00 mode. It is shown that the induced birefringence partly lifts the degeneracy of the eigenfrequency spectrum, which–in the absence of birefringence–is analogous to the spectrum of a hollow resonator in the form of a circular ellipsoid.
