    A complete picture of the evolution of a plane wave passing through axicon-lens system was theoretical analyzed, numerical simulated and experimental demonstrated. A non-diffracting beam was obtained as plane wave passing axicon. A bottle beam can be generated if a focal lens kept within the maximum non-diffracting distance, and the size of the bottle beam easy adjusted by changing the focal length of the lens. As the beam further propagation, self-reconstruction of the Bessel beam generated. The divergence of the self-reconstruction beam causes the beam intensity decreasing and the bright spot size increasing as the beam propagating. A second focal lens was introduced to rectify the divergence of the self-reconstruction beam. The intensity profiles of the beam cross-section were captured using the optical system of the microscope and CCD camera. The theoretical analysis and numerical simulation were confirmed by the experimental results.
