In this paper, attention is focused on the intensity moments of the Hermite Cosh Gaussian (HChG) laser beams from the zero order to the fourth order. The frequently used parameters such as the power in bucket (PIB), the beam width, the curvature radius, the far field divergence, the M 2 factor, the Rayleigh length and the kurtosis are calculated in terms of the intensity moments. Figures show the influence of the mode index and the decentered parameter, which are the critical parameters of the HChG beams. Moreover, the center of the gravity of the radiation field and the symmetry are discussed along with the propagation axis. Finally, the power fraction within the beam width defined by the second moments is illustrated with numerical method.
