“…In this context, the direction of transverse displacement of the incident beam has not been important: with respect to this direction, the diffracted beam deformation caused by the displacement has always been the same [33]. For the volume HEs, as well as for the thin HEs with high diffraction angles [36], the asymmetry of the diffracted beam profile cannot be neglected and this implies different responses of the diffracted beam profile to the x-and y-oriented misalignments.…”

“…In the most common case, the intensity profile of the beam is characterized by the coordinates of centre of gravity (CG) of the beam [33,36,44], which are defined by the relations 2 2 2 2 2 2 2 2 0 2 2 2 0 2 2 2 2 2 2 2 ( , , ) ( ) ( ) ( , , )…”

“…Their properties have been studied in many experimental and theoretical works [17,24,[25][26][27][28][29][30][31][32][33][34][35][36], though practically all of the results are limited to the case of a thin (plane) HE (in this case the generated OV-beams can be united within a special class of 'Kummer beams' [30], or 'hypergeometric-Gaussian beams' [34]). However, operation of such thin HEs is not free from essential drawbacks: simultaneous diffraction to a number of orders leads to low intensities of any of the individual diffracted beams, each diffracted OV-beam is rather sensitive to uncontrollable conditions of HE-induced transformations, and the whole OV-generation procedure suffers from low angular and spectral selectivities.…”

“…All of these points make it highly relevant to study in detail the role and significance of the diffracted-beam distortions appearing due to nonideal arrangement of the incident beam and the HE the with EPS. A general approach to this problem has been developed in application to thin HE [33,36]. In the present work, we generalize it and apply to the OV-beams generated by thick HEs, basing on the theory developed earlier for perfectly aligned volume HEs with EPSs [37].…”

Abstract. Based on the linear theory for optical vortex (OV) formation in volume holographic elements (HE) with embedded phase singularity (A. Bekshaev et al., Opt. Commun. 285 (2012) 4005), we analyze theoretically the OV-beams obtained when the incident Gaussian beam axis deviates from the optical axis of the HE. For different displacements of the incident beam with respect to the HE centre, the spatial characteristics of the diffracted beams and their evolution during the post-HE propagation are investigated numerically with allowance for the radiation extinction in the HE depth. A special attention is paid to behaviour of the beam centroid (centre of gravity) trajectory. The sensitivity of the generated OV-beam profile to the incident beam misalignments can be used for the output beam shaping and control, in particular, for compensation of the OV-beam distortions associated with the light extinction.

“…A possible way for obtaining optical vortices is based in the use of fork like holograms, as has been widely studied [7][8][9][10][11][12][13][14]. In order to test the vortices an interferometric set-up is required.…”

ABSTRACT:We present a compact design to generate and test different vortex beams with orbital angular momentum (OAM). The design consists of a mask that contains both, a binary amplitude hologram and a pinhole. When the mask is illuminated and the pinhole is blocked, the hologram produces a vortex beam with OAM whose intensity distribution can be observed in the far field. When the pinhole is unblocked a reference wavefront is generated which allows testing interferometrically the spatial phase distribution of the beam. We numerically simulate the experiment for two kind of beams containing OAM: Laguerre-Gaussian like vortex beams and Mathieu beams.Key words: optical vortex; computer generated holograms; fork hologram; orbital angular momentum; Mathieu beams. RESUMEN:Presentamos un diseño compacto para generar y testear diferentes vórtices ópticos con momento angular orbital (OAM). El diseño consiste en una máscara que contiene un holograma binario y un pinhole. Cuando la máscara es iluminada y el pinhole se bloquea el holograma produce un vórtice óptico con OAM cuya distribución de intensidades se observa en el campo lejano. Cuando se deja pasar la luz proveniente del pinhole se genera una onda de referencia que permite testear de manera interferométrica la distribución especial de fase del haz. Mostramos simulaciones numéricas del experimento para dos clases de haces conteniendo OAM: un haz tipo Laguerre-Gauss y un haz Mathieu.Palabras clave: vórtices ópticos; holograma generado por computadora; holograma tenedor; momento angular orbital; haces Mathieu.
