“…An important parameter in the dynamic propagation is the initial launch angle [18,19] which can be used to obtain optimal control of the ballistic trajectory. Recently, several authors have addressed the propagation properties of AiBs to study of circular Airy beams (CAiBs) [20,21,22] and radial array Airy beams [23,24] for optical trapping due to it unique abruptly auto-focusing characteristics where optical spot obtained in focal field can be used for simultaneous trapping of multiple particles [25,26,27,28,29].…”

The Airy array beams are attractive for optical manipulation of particles owing to their non-diffraction and auto-focusing properties. An Airy array beams is composed of N Airy beams which accelerate mutually and symmetrically in opposite direction, for different ballistics trajectories, that is, with different initial launch angles. Based on this, we investigate the optical force distribution acting on Rayleigh particles. Results show that is possible to obtain greater stability, for optical trapping, increasing the number of beams in the array. Also, the intensity focal point and gradient and scattering force of array on Rayleigh particles can be controlled through a launch angle parameter.

“…The process of obtaining numerical fields and non-diffracting beam holograms allows us to generate arrays or a certain spatial distribution of N non-diffracting beams. Arrays of non-diffracting beams are interesting for possible applications in optical tweezers, optical communications for a system with multiple communication channels and for generating solitons in a non linear crystal [24,25]. From the fields of these different non-diffracting beams Ψ(x, y, z), we consider the origin of the displaced coordinate system on the plane transverse to the direction of propagation (x±δx; y±δy).…”

This work presents, for the first time the optical generation of non-diffracting beams via photorefractive holography. Optical generation of non-diffracting beams using conventional optics components is difficult and, in some instances, unfeasible, as it is wave fields given by superposition of non-diffracting beams. It is known that computer generated holograms and spatial light modulators (SLMs) successfully generate such beams. With photorefractive holography technique, the hologram of a non-diffracting beam is constructed (recorded) and reconstructed (reading) optically in a nonlinear photorefractive medium. The experimental realization of a non-diffracting beam was made in a photorefractive holography setup using a photorefractive Bi12SiO20 (BSO) crystal as the holographic recording medium, where the non-diffracting beams, the Bessel beam arrays and superposition of co-propagating Bessel beams (Frozen Waves) were obtained experimentally. The experimental results are in agreement with the theoretically predicted results, presenting excellent prospects for implementation of this technique for dynamical systems at applications in optics and photonics.

In this work, we present the experimental optical trap of microparticles with an Airy beams array using a holographic optical tweezers. The Airy beams array are attractive for optical manipulation of particles owing to their non-diffracting and autofocusing properties. An Airy beams array is composed of N Airy beams which accelerate mutually and symmetrically in opposite direction, for different ballistic trajectories, that is, with different initial launch angles. Based on this, we developed a holographic optical tweezers system for the generation of non-diffracting beams and with it, we investigate the distribution of optical forces acting on microparticles of an Airy beams array. The results show that the gradient and scattering force of array on microparticles can be controlled through a launch angle parameter of Airy beams. In addition, it's possible to obtain greater stability for optical trap using an Airy beams array, with interesting possibilities for trapping and guiding of microparticles in a controllable way that can be applied in optical, biological and atmospheric sciences.Particularly, the Airy beams (AiBs) has attracted great interest recently in optical tweezers, for trapping and guiding of micro and nano-particles [16,17,18,19,20,21], due to their unusual features such as the ability to remain diffraction-free over long distances while they tend to freely accelerate during propagation [10,11,12]. An important parameter in the dynamic propagation is the initial launch angle which can be used to obtain optimal control of the ballistic trajectory [22,23,24]. Recently, several authors have addressed the propagation properties of AiBs to study of circular Airy 1
