Virtual Sources for a Sinh-Gaussian Beam
On the basis of the superposition of beams, a group of virtual sources that generate a sinh-Gaussian wave is identified. A closed-form expression is derived for the sinh-Gaussian wave, which, in the appropriate limit, yields the paraxial approximation for the sinh-Gaussian beam. From this expression, the paraxial approximation and the nonparaxial corrections of all orders for the corresponding paraxial sinh-Gaussian beam are determined.
