Generation of high conical angle Bessel–Gauss beams with reflective axicons
Applied optics, 2018•opg.optica.org
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.
