Paper Abstract

Methods are presented for calculating the radiation intensity in the focal region resulting from the focusing of a laser beam by a spherical surface lens. An approach based upon Fourier optics is employed to include the effects of aberrations as well as diffraction and interference, and digital signal processing techniques are used to speed the calculations. Calculated results are displayed on a digital image processor to aid in visual interpretation. Sample calculations are presented for intensity fields in the transverse and meridional planes of the focal region for circular, gaussian and annular laser beams incident on the lens perpendicularly and at small oblique angles.
