| 英文摘要 | bessel beam can overcome the limitation of the rayleigh range of gaussian beam with the same spot size propagation without any spreading due to diffraction, which is considered as an useful function in guiding particles in the next generation of optical tweezers. the mathematical description of the bessel beam generated by an axicon is usually based on the fresnel diffraction integral theory. in this paper, we deduce another type of analytic expression suitable for describing the beam profile generated from the axicon illuminated by the gaussian beam based on the interferential theory. compared with the fresnel diffraction integral theory, this theory does not use much approximation in the process of mathematical analysis. according to the derived expression, the beam intensity profiles at any positions behind the axicon can be calculated not just restricted inside the cross region as the fresnel diffraction integral theory gives. the experiments prove that the theoretical results fit the experimental results very well.
