The diffraction-free Bessel beams were generated using two different base angle axicons. The optical intensity distribution in a single Bessel beam and two Bessel beams interference were analyzed, and the characteristics of the generated bottle beams in a complete period were also analyzed. The transverse optical intensity distribution of the beam along the propagation distance was simulated numerically and the related experiments were given. The central spot size of a single Bessel beam and two Bessel beams interference were measured and the results were coincident with the theoretical analysis.
