title: Coherence theoretic algorithm to determine the transverse-mode structure of lasers.
abstract: We introduce an algorithm to determine the relative modal weights of a laser beam with Hermite-Gaussian modes. The method is based on coherence theory of stable resonator modes in the space-frequency domain. Numerical simulations are presented that show that the algorithm is not sensitive to moderate levels of noise.
