Photophoretic Asymmetry Factor of On-Axis Non-Diffracting Frozen Waves and Dielectric Micro-Spheres

Abstract

Photophoretic asymmetry factors are theoretically investigated for on-axis nondiffracting frozen waves illuminating rigid dielectric micro-spheres using the generalized Lorenz-Mie theory. The ability to exert positive or negative photophoretic forces is considered for optical trapping applications.
