Title: The<i>M</i><sup>2</sup>factor of hermite-cosh-gaussian beams
Abstract: Abstract Based on the second-order moments method, the closed-form expression for the M 2-factor of Hermite-cosh-Gaussian beams is derived, which depends on the beam order n and decentred parameter a. The result shows a more general characteristic, because cosh-Gaussian, Hermite-Gaussian and fundamental Gaussian beams can be regarded as the special cases of Hermite-cosh-Gaussian beams.
