Paper Abstract

The focusing of the focused Gaussian beam by a spherical aberration micro-lens is investigated by Monte Carlo simulation. This method takes into the images affected by the primary even higher orders aberration with no paraxial approximation. The effect of the negative spherical aberration on the radial intensity distribution, spot size and focal shift are discussed. The simulation results show that when the Gaussian beams are focused by a lens with spherical aberration, the radial intensities distributions in the geometrical and best focal plane had two maxima, and the maxima point are not located in the optical axis. And with the Fresnel number increasing, the simulation focal shift curve approach the curves calculated by the formula for an aberration-free lens.
