Abstract
A virtual source that generates a Hermite–Gauss wave of mode numbers and is introduced. An expression is obtained for this Hermite–Gauss wave. From this expression, the paraxial approximation and the first 3 orders of nonparaxial corrections for the corresponding paraxial Hermite–Gauss beam are determined. When both and are even, leading to maximum amplitude along the axis, the number of orders of nonvanishing nonparaxial corrections is found to be equal to .
