摘要：

Analytical expressions for the M-2 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. (C) 1999 Optical Society of America OCIS codes: 350.5500, 030.4070, 140.3300.
