An analytical expression to study the propagation properties of an Airy-Hermite-Gaussian beam
pas... more An analytical expression to study the propagation properties of an Airy-Hermite-Gaussian beam passing through an apertured misaligned optical system is developed, in this paper, by using the generalized Huygens-Fresnel diffraction integral and by means of expansion of the hard-edged aperture into a finite sum of complex-Gaussian functions. Some particular cases are deduced from the main theoretical formalism of our work. The propagation characteristics of the considered beam through an apertured aligned and misaligned circular thin lens are investigated numerically. The results of this finding show that the output beam shape remains unchanged and similar to that of the incident beam. However, it is slightly decentred in x or/and y directions and its deflection is related to the misalignment parameters. Keywords: Generalized Huygens-Fresnel diffraction integral; Airy-Hermite-Gaussian beam; Aligned optical system; Misalignment; Circular aperture; Circular thin lens.

passing through an apertured misaligned optical system is developed, in this paper, by using the
generalized Huygens-Fresnel diffraction integral and by means of expansion of the hard-edged aperture
into a finite sum of complex-Gaussian functions. Some particular cases are deduced from the main
theoretical formalism of our work. The propagation characteristics of the considered beam through an
apertured aligned and misaligned circular thin lens are investigated numerically. The results of this
finding show that the output beam shape remains unchanged and similar to that of the incident beam.
However, it is slightly decentred in x or/and y directions and its deflection is related to the misalignment
parameters.
