High order modes in a spherical Fabry-Perot resonator
Abstract
A theoretical and experimental study was made to examine the accuracy of an approximate solution to the wave equation for a large-aperture Fabry-Perot laser resonator at X-band frequencies. The resonant frequency was found to deviate from the predicted value by as much as 2 percent for high radial-mode numbers. Two first-order perturbation calculations, including a neglected term in the wave equation and the nonsphericity of the constant-phase surfaces, yielded resonant frequencies in agreement with experiment.
