Abstract
In this work, we use the analytical expression of the propagation of Finite Olver-Gaussian beams (FOGBs) through a paraxial ABCD optical system to study the action of radiation forces produced by highly focused FOGBs on a Rayleigh dielectric sphere. Our numerical results show that the FOGBs can be employed to trap and manipulate particles with the refractive index larger than that of the ambient. The radiation force distribution has been studied under different beam widths. The trapping stability under different conditions is also analyzed.
Highlights
In recent years, the accelerating finite Airy beam has been introduced within the framework of laser optics field by Siviloglou et al [1] [2], on the basis of the result published by Berry and Balzas [3], in the context of the quantum mechanics, whose have introduced the Airy wave packet function as a solution of the Schrödinger equation in 1979
This leads to its experimental realization where most of the interesting properties were observed directly in many configurations [2], and the study of its ballistic dynamics shows that these waves follow parabolic trajectories similar to these of projectiles moving under the action of uniform gravitational field [4] [5]
We simulate the radiation force produced by the incident focused Finite Olver-Gaussian beams (FOGBs) considered in one-dimension
Summary
The accelerating finite Airy beam has been introduced within the framework of laser optics field by Siviloglou et al [1] [2], on the basis of the result published by Berry and Balzas [3], in the context of the quantum mechanics, whose have introduced the Airy wave packet function as a solution of the Schrödinger equation in 1979 This new laser beams family exhibits many important characteristics, which permit them good candidates in several applications such as manipulating, trapping and transport of particles. Note that the new beams family, called “Finite Olver-Gaussian beams”, is introduced within the optic field and their characteristics and propagation properties in aligned and misaligned optical systems are studied and examined for the first time by our research group [37]-[39]
