Analytic expressions for aperture output mode of a multiple pass ring resonator have been derived using ABCD matrices and diffraction integral function of multi element resonator. It is proved by theoretically analysis and numerical calculations, that low rank Bessel beam is stable in the multiple pass ring resonator. The characteristics of lose and output of low rank Bessel beam have also been studied theoretically by numerical calculations.
