Optical resonators and Gaussian beams

Laguerre-Gaussian Modes

If the resonator symmetry is mostly circular, the modes exhibit a cylindrical symmetry described by the Laguerre polynomials. The mathematical method is the same as the one described for Hermite-Gaussian modes. The figure 21 describe the intensity distribution for such modes.
