Paper Abstract

This paper presents an analytical model to evaluate both the longitudinal and the transversal intensity distributions of beams emitted by laser diodes, focused by a thin lens and diffracted by a circular aperture of arbitrary radius. The model evaluates the diffraction field in systems with any Fresnel number and has been validated successfully comparing theoretical results with experimental ones.
