ABSTRACT
We report the generation of Bessel-Gauss beams of high conical angle, up to 35 deg, using reflective off-axis axicons and a magnification optical system. We experimentally characterize the beams with three-dimensional scans. The high precision of fabrication of the axicons in the vicinity of the axicon singularity allows us to generate a beam with intensity distribution close to analytical description.
