The role of Airy beam parameters in the optical manipulation problems

Abstract

The Airy beam is of specific interest for optical manipulation due to its diffraction-free propagation in the paraxial approximation. Micro- and nanoparticle trapping is accomplished by forces and angular momentum which are determined by the light beam energy, orbital momentum, spin momentum and angular momentum densities. The dependence of these quantities on such parameters of the Airy beam as its polarization, initial launch angles, and truncation factor are found in the first approximation in the angle of divergence.
