Acoustooptic refraction-influenced generation of tunable incomplete Airy beams

Abstract

In the process of acoustooptic refraction of an incident-finite- aperture light beam on a standing acoustic wave, there arises a cubic phase modulation of the beam in passing through an acoustooptic cell. After the Fourier transformation of the transmitted field, an Airy-type beam is formed with varying in time parameters. The propagation of such a beam is described explicitly with diffraction integral. By using the numerical simulation, it is established that the transverse intensity profile, acceleration and additional modulation of oscillations of a generated incomplete Airy beam are dependent on the frequency and power of an acoustic wave.

Acousto-optical modulation of airy light beams in crystals

“…In order to obtain finite-power AB, amplitude of which has linear exponential modulation, it was necessary to use a Gaussian beam instead of a plane wave in the same Fourier transform scheme. Papers [7,8] provide an overview of self-accelerating Airy beams, features of their generation, control, and potential applications.…”

Generation of Airy beams with transmissive cross-polarization conversion metasurfaces

“…Moreover, the propagation dynamics of Airy beams in nonlinear media were also investigated [18]. And various methods to generate the Airy beams in the optical region have been proposed, the conventional ways of generating the Airy beams are usually based on spatial light modulators [19][20][21], lens systems [22][23][24] and phase plates [25]. However, these proposed approaches are restricted in practical application since these Airy beams generators are bulky and difficult to integrate with other optical devices.…”

Anomalous Propagation Characteristics of Airy Beam in Nonlinear Kerr Media

“…This study on the new Airy beams and other non-diffractive beams has become a hot area in recent years. Recently, most attention has been concentrated on the generation of Airy beams [4][5][6][7][8], particular Airy beams [9][10][11][12][13], the control of particular beams [14][15][16] and the potential application of these beams, such as the directional control of particles [17] and the generation of light bullets [18,19].…”
