Abstract
Based on the hankel waves theory, formation principle of Bessel beam is analyzed, self-reconstruction behavior of zero-order and high-order Bessel beam is also explained commendably. Based on the diffraction theory and the transmission model under the collins formula conditions, optical intensity of high-order Bessel beam after a circular obstacle is simulated. Result shows that the high order Bessel-Gauss beam have similar self-reconstruction behavior with zero-order Bessel beam. In terms of the experiment, first-order Bessel-Gauss beam is generated by focusing of vortex beam with an axicon. This Bessel-Gauss beam passes though an on-axis circular obstacle, an on-axis square obstacle and an off-axis square obstacle, and the self-reconstruction properties of the high-order Bessel-Gauss beams are verified. Experimental results agree well with the theoretical analysis.
