  • Based on the 16 phase level binary optical elecment(BOE) designed to convert a given single-mode He-Ne laser beam into a ring-shaped intensity distribution,its shaping effect is numerically simulated for different input beam radii.The simulation results show that the relative mean-square deviation of the shaped amplitude is less than 5% when the difference between the input beam radius and the designed one is within the range of ±50μm.Furthermore,experiment results have been presented for the case that the input beam radius is 1.745mm and the -wavelength for the semiconductor is 660nm.

Abstract: Based on the 16 phase level binary optical elecment(BOE) designed to convert a given single-mode He-Ne laser beam into a ring-shaped intensity distribution,its shaping effect is numerically simulated for different input beam radii.The simulation results show that the relative mean-square deviation of the shaped amplitude is less than 5% when the difference between the input beam radius and the designed one is within the range of ±50μm.Furthermore,experiment results have been presented for the case that the input beam radius is 1.745mm and the -wavelength for the semiconductor is 660nm.
