Abstract
Based on the second moments method and orthogonal basis mode expansion,analytical expressions for the M2 factor and mode coherence coefficients of cosh-Gaussian beams have been derived, thus analysis of mode correlation and mode structure of cosh-Gaussian beams is available. A simple method has been also proposed to produce cosh-Gaussian beams in the laboratory.
