Coupling coefficients of mismatched and misaligned Gauss–Hermite and Gauss–Laguerre beams
Abstract
The coupling coefficients of two misaligned and mismatched sets of Gauss-Laguerre (Gauss-Hermite) modes are calculated by using the generating function of the Hermite polynomials. Knowledge of these coefficients is important in calculating the sensitivity of low-gain lasers to the misalignment of the optical resonators, an example being provided by free-electron-laser devices built on storage rings.
