In this paper, axicon element is used to construct superresolution apodizer. The intensity distribution in focal region of focusing laser optical system is investigated, and the diameter of the output annular beam is tunable, which means the superreso-lution effect is controllable. Simulation results show that this kind of apodizer can reduce the center focal spot for superresolution.
