Nanosecond pulsed Bessel–Gauss beam generated directly from a Nd:YAG axicon-based resonator

Abstract

We present what we believe to be a novel, simple, and compact axicon-based resonator Nd:YAG laser in which a nanosecond pulsed Bessel–Gauss beam is generated directly for the first time. Using the theory of the Bessel–Gauss beam, theoretical analysis and numerical simulation are consistent with the experimental results.
