Bessel–Gauss beam optical resonator
New, G. H. C.
In a simple picture, a Bessel beam is views as a transverse standing wave formed in the interference region between incoming and outgoing conical waves. Bases on this interpretation we porpose an optical resonator that supports modes that are approximations to Bessel-Gaus beams. The Fox-Li algorithm in two transverse dimensions is applied to confirm the conclusion.
