Abstract

The near and far field intensity distribution as well as the beam quality of the combination between the hollow beam generated by double axicons and the Gaussian beam were simulated in this paper. The simulation results revealed that several parameters like the interval between two axicons and the phase difference between the two beams would influence the intensity distribution of the combined beam, especially the phase difference between the hollow beam and Gaussian beam which could transforms the far-field intensity distribution into quasi-hollow distribution or peak shaped distribution and was of great potentiality in the industry application.
