Calculating the Fine Structure of a Fabry-Perot Resonator using Spheroidal Wave Functions
| Abstract | A new set of vector solutions to Maxwells equations based on solutionsto the wave equation in spheroidal coordinates allows laser beams to bedescribed beyond the paraxial approximation. Using these solutionsallows us to calculate the complete first-order corrections in theshort-wavelength limit to eigenmodes and eigenfrequencies in aFabry-Perot resonator with perfectly conducting mirrors. Experimentallyrelevant effects are predicted. Modes which are degenerate according tothe paraxial approximation are split according to their total angularmomentum. This includes a splitting due to coupling between orbitalangular momentum and spin angular momentum. |
