Abstract

Abstract

The distribution of light field behind a vaulted axicon is calculated with diffraction theory and simulated with software, the result demonstrates that vaulted axicons can be used to generate bottle beams. The light intensity is simulated again after changing the base angle or the focal length, the result shows that the base angle of vaulted axicons has some effect on the period and the number of dark regions of bottle beams, while the focal length of plano-convex lenses on the top of vaulted axicons is related to the number of dark regions but has little effect on the period. The required bottle beam can be obtained according to adjusting the relevance parameters in practical application.
