We present the experimental generation and analysis of both the intensity and phase of an optical vortex beam originating from a superposition of Airy-vortex beams. A new theoretical proposal is accessible to generate an array of Airy-vortex beams (AiVBs) from a superposition of N identical AiBs symmetrically located with respect to the propagation axis, where each beam is superimposed with OV and are characterized by the same topological charge l. Additionally, a single experimental apparatus enables both the optical generation and reconstruction of computer-generated holograms implemented on a spatial light modulator and its phase analysis by digital holography. The experimental results agreed with the theoretical predictions. The array of Airy-vortex beams has potential applications for trapping and rotating micro-particles in optical tweezers, modulation in optics communications, optical metrology, and others in optics and photonics. arXiv:1909.05031v1 [physics.optics]

“…Particularly, these methods have generated experimental results of high quality and fidelity optical beams reconstruction compared to the theoretical predicted, because the holographic technique is an extremely accurate tool in the reconstruction of amplitude and phase of optical waves. Recent works using these tools has explored applications in optical tweezers for manipulation of many particles [27], in image analysis of micro-structures and biological microscopy [28,29]. Particularly, in this work from the field that described the Airy beams Eqs.…”

In this work, we present the theoretical and experimental study of the propagation of Airy beams when passing through two convex lenses with different focal distances. The theoretical analysis is presented from a matrix optical model for an Airy beam. The experimental results are obtained in a holographic setup for experimental generation of Airy beams based on the holographic reconstruction system of computer generated holograms (CGH) implemented electronically in a spatial light modulator (SLM) and a 4f Fourier transformation system. These are in agreement with the theoretical prediction. The novelty of this work went to show the evolution of the Airy beam propagation for different convex lenses in a 4f system and its dependence on focal distances. These are important for the control and manipulation of Airy beams; and, they show new possibilities of applications of the Airy beams in optical tweezers, optical communications and optical guidance.
