Abstract: The characteristics of multielement optical resonators,in particular,the resonator with an internal lens and telescopic resonator which can be represented in terms of fractional Fourier transforms(FRFTs) have been studied by means of the ABCD matrix method.Then,starting from the generalized Huygens-Fresnel diffraction integral,the two-dimensional diffraction integral of optical resonators expressed as FRFTs has been derived and the corresponding matrix formulation has been given and discussed.
