A novel optical element, vaulted axicon, is proposed for the first time in this paper. We analyze the distribution of light field with diffraction theory, and simulate the intensity distribution behind vaulted axicon. The result shows that multi-bottle beam can be obtained after a plane wave has passed through an vaulted axicon, moreover the intensity of the bottle beam is very high in the focal region because of the energy of spherical wave is significant concentrated in this region. The simulation and comparison show that the intensity around the bottle beam generated by vaulted axicon is far higher than that generated by superposition of two Bessel beams, therefore the particle trapping efficiency can be significantly increased. By comparing the scattering forces of bottle beam generated by the two methods, we demonstrate that the bottle beam generated by vaulted axicon is superior in particle trapping.
