Simple formula for a Gaussian beam with general astigmatism in a homogeneous medium

A simple analytical formula that describes the evolution of a Gaussian beam with general astigmatism in a homogeneous medium is obtained. The quadratic form matrix, which determines the transverse distribution of the field in the beam for an arbitrary value of the longitudinal coordinate, is represe...
