✦ Synopsis


We present what we believe the first experimental observation of a nanosecond zero order pulsed Bessel beam generated from an unstable resonator based on an axicon. The field distribution at the output coupler is simulated by means of Fox-Li iterative computation. It is shown that the experimental result is consistent with the numerical simulation. The application field and forecast of the zero-order Bessel beams are very wide, such as precision cutting and micro-operation experiment. Our experiments offer a new way to output zero-order Bessel beams directly.
