“…15 The Airy modes also exist in the form of non-diffracting surface plasmon, [16][17][18] self-accelerating acoustics, 19 electron beams, 20 as well as spatiotemporal non-spreading light bullets. 21 In the present work, an ultra-long needle focus was experimentally generated through the creation of a rectangularly symmetric Airy beam (SAB) 22,23 with binary spectral amplitude modulation. The SAB first autofocuses and appears with a single central lobe, then the lobe splits into four Airy main lobes, and it looks like a combination of four Airy beams with an outward acceleration.…”

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.

“…In addition, the Airy beam proves very resilient to perturbations, as it is able to linearly reconstruct (self-heal) itself 5 . Further research activity on Airy beams in the non-linear regime has revealed stationary non-linear 1D solutions 6 , (3 þ 1)D non-linear light bullets 7 , solitons in self-defocusing media 8 and other newly observed spatial mechanisms 9,10 . Recently, the Airy wavepacket concept has also been demonstrated for electron packets 11 .…”

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.

“…18 Such third order phase control leads to temporal pulse shapes that are termed Airy pulses. 19 Furthermore, it was recently shown that the volume of laser-excitation in bulk water can be controlled by such pulse shapes. 20 By using positive third order dispersion laser pulses, the area of excitation can be reduced by nearly a factor of two while the depth of the excitation reached much deeper inside the bulk water sample.…”

We show that spectral phase shaping of fs-laser pulses can be used to optimize laser-cell membrane interactions in water environment. The energy and peak intensity thresholds required for cell poration with single pulse in the nJ range can be significantly reduced (25% reduction in energy and 88% reduction in peak intensity) by using temporal Airy pulses, controlled by positive third order dispersion, as compared to bandwidth limited pulses. Temporal Airy pulses are also effective to control the morphology of the induced pores, with prospective applications from cellular to tissue opto-surgery and transfection
