Abstract

Analytical expressions for the M2 factor and the mode-coherence coefficients of hyperbolic-cosine– (cosh-) Gaussian beams have been derived, and a simple method of producing cosh-Gaussian beams in an experiment, superposition of two decentered Gaussian beams, has been proposed. Our results will be useful for studying more-general Hermite–sinusoidal-Gaussian beams.
