✦ Synopsis

A refractive system is designed to convert a high-power annular beam into a circular Bessel beam. The input and output surface of the proposed system is derived. We provide cubic polynomial approximation of the surface proÿles. A ray tracing through the complete system is provided to verify the design. The design parameters can be selected to choose the desired beam power in the central lobe and length of the refractive system.
