Nanosecond zero-order pulsed Bessel beam generated from unstable resonator based on an axicon
Unstable resonator Axicon Zero-order Bessel–Gauss beams
2013/7/2
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 outpu...
