Abstract

Based on an axicon-based Bessel-Gauss resonator

a nanosecond high power non-diffracting pulsed Bessel-Gauss beam was generated directly from a flashlamp pumped

switched Nd:YAG laser for the first time.The experimental results were analyzed using the Bessel-Gauss model deduced from the diffraction integral theory and they were consistent with the numerical simulation. On the other hand

by a high stability nanosecond Gaussian pulse generated from a

switched Nd:YAG laser with an anti-resonant ring and pulse shaping passing through an axicon

a nanosecond non-diffracting zero order Bessel beam was obtained using the passive method.A film-scanning was used to record the fine structure of the intensity profile

and a beam analyzer to measure the pulse characteristics. The measured results show that the central spot size is about 90 μm and the peak power density of the central spot reaches to 2.3×10

W/cm

.Finally

the active and passive schemes for generating the nanosecond non-diffracting beam were compared and analyzed.
