“…In recent years, Airy beams have attracted great interest due to their unique features, including non-spreading, self-healing, self-acceleration (even in the absence of external force) and parabolic trajectories [1][2][3][4][5]. These characteristics lead them to be good candidate in many applications such as optical micro-manipulation [6], curved plasma channel generation [7,8], optical microscopy and scanning microscopy using optical Airy bullets [9], vacuum electron acceleration [10], trapping and guiding microparticles [11,12].…”

“…Compared to a single conventional Airy beam, the creation of Airy Array beam can enable the parallel processing with intrinsic high processing efficiency for various applications; i.e., nanofabrication, generation of curve plasmon channel, light sheet microscopy, etc. Besides, compared to the Airy beam generated by Fourier transform of Gaussian beam modulated by a cubic phase [4], the Airy transform setup used in this work presents some practical advantages in controlling the output beam [22,23]. It is provided that when the incident Gaussian beam is translated by a vector in the input plane, the output Airy beam will be translated by the same vector in the output plane.…”

Abstract-In this work, a novel family of Finite Airy array beams have been produced by an optical Airy transform system illuminated by Gaussian Array beams. Based on the generalized HuygensFresnel integral, an analytical expression is developed to describe the pattern properties of the beam generated at the output plan of the optical system. The well-known Finite Airy beam generated from the fundamental Gaussian beam using an optical Airy transform system is deduced, here, as a particular case of the main result of the actual study. Numerical calculations are performed to show the possibility to create a multitude of Finite Airy array beams with controllable parameters depending on the number of beamlets, the distance between the adjacent modules and the positions and orientations of the beamlets.

“…7,8 Such an Airy beam exhibits Airy like pattern in the transverse plane and a ballistic trajectory for the central lobe during propagation. 9 The Airy beam possessing gradient force field acts as a snow-blower, enabling the clearing of particles in a specific spatial region. 10 The self-accelerating Airy beam created with femtosecond intense pulses could induce a bent plasma channel 11 for conductive purpose.…”

Needle-like electromagnetic field has various advantages for the applications in high-resolution imaging, Raman spectroscopy, as well as long-distance optical transportation. The realization of such field often requires high numerical aperture (NA) objective lens and the transmission masks. We demonstrate an ultralong needle-like focus in the optical range produced with an ordinary lens. This is achieved by focusing a symmetric Airy beam (SAB) generated via binary spectral modulation with a digital micromirror device. Such amplitude modulation technique is able to shape traditional Airy beams, SABs, as well as the dynamic transition modes between the one-dimensional and two-dimensional (2D) symmetric Airy modes. The created 2D SAB was characterized through measurement of the propagating fields with one of the four main lobes blocked by an opaque mask. The 2D SAB was verified to exhibit self-healing property against propagation with the obstructed major lobe reconstructed after a certain distance. We further produced an elongated focal line by concentrating the SAB via lenses with different NAs and achieved an ultralong longitudinal needle focus. The produced long needle focus will be applied in optical, chemical, and biological sciences.

“…3). The most notable feature of the linear Airy beam is the transverse acceleration, which causes the beam to propagate in a parabolic trajectory 4 , while keeping a constant central lobe diameter. This exotic behaviour is forced by a strong spatial cubic phase which is imprinted on the beam profile.…”

Sharply autofocused ring-Airy beams transforming into non-linear intense light bullets

et al. 2013

Controlling the propagation of intense optical wavepackets in transparent media is not a trivial task. During propagation, low-and high-order non-linear effects, including the Kerr effect, multiphoton absorption and ionization, lead to an uncontrolled complex reshaping of the optical wavepacket that involves pulse splitting, refocusing cycles in space and significant variations of the focus. Here we demonstrate both numerically and experimentally that intense, abruptly autofocusing beams in the form of accelerating ring-Airy beams are able to reshape into non-linear intense light-bullet wavepackets propagating over extended distances, while their positioning in space is extremely well defined. These unique wavepackets can offer significant advantages in numerous fields such as the generation of high harmonics and attosecond physics or the precise micro-engineering of materials.
