Features of Photonic Nanojet Formation near Surfaces of Spherical Microparticles Illuminated by a Focused Laser Beam

摘要

Optical field parameters in a "photonic nanojet" formed near surfaces of dielectric spherical microparticles illuminated by a focused laser beam are studied theoretically. The influence of the beam waist on "photonic nanojet" parameters (length, width, and intensity) is analyzed.
