Abstract
A novel and efficient method for Bessel beams generation is proposed. It relies on using a toroidal zone plate as an element forming the ring focus and subsequent Fourier transforming of the ring focus into the Bessel beam. The proposed solution, thanks to focusing of all illuminating wave into the ring focus allows to achieve greater efficiency than earlier solutions. Moreover it enables to generate higher order Bessel beams by adding a linear angular phase term to the transmittance of the zone plate. The proposed method is confirmed by numerical simulations.
