Abstract
Based on a rigorous far field solution of the Helmholtz equation, a new method to describe the propagation of the offaxial Gaussian wave is presented. The amplitude and phase distribution, beam spot size, divergence angle, and the relation of the conservation of energy are discussed. It is found that for any Gaussian source the maximum divergence angle is shown to be 65.5.
