Abstract

Features of formation "photonic nanojets" (PNJs) near the surface of spherical dielectric microparticles irradiated by a spatially limited laser beam are theoretically investigated. The influence of the waist size of a light beam with the Gaussian transverse intensity profile on PNJ spatial parameters and peak intensity is found for the first time.
