“…Nonlinear three-wave mixing process have also been employed in the generation of an Airy beam from a pump under phase matching conditions [100,101]. During harmonic generation of abruptly autofocusing beams it was shown that the high harmonics preserve the phase distribution of the fundamental beam [102].…”

Over the last dozen of years, the area of accelerating waves has made considerable advances not only in terms of fundamentals and experimental demonstrations but also in connection to a wide range of applications. Starting from the prototypical Airy beam that was proposed and observed in 2007, new families of accelerating waves have been identified in the paraxial and nonparaxial domains in space and/or time, with different methods developed to control at will their trajectory, amplitude, and beam width. Accelerating optical waves exhibit a number of highly desirable attributes. They move along a curved or accelerating trajectory while being resilient to perturbations (self-healing), and, are diffraction-free. It is because of these particular features that accelerating waves have been utilized in a variety of applications in the areas of filamentation, beam focusing, particle manipulation, biomedical imaging, plasmons, and material processing among others.

“…And the authors generated the multi-focus auto-focusing beams at the focusing plane by modifying the frequency spectrum of a symmetric Airy beam with a Gaussian band elimination filter [23]. Unlike the multi-focus CABs with off-axis focus at the focusing plane, there are methods to generate the multifocusing beams along the optical axis, such as by introducing two different initial launch angles [24], under the action of a converging lens [25][26][27][28], and by introducing hyperbolic umbilic function modulation [29]. Despite existing methods for modulating CABs to generate multi-focal abruptly autofocusing beams, it is still difficult to obtain multi-focus autofocusing beams with equal intensity focus along the optical axis.…”

The auto-focusing property of the optical beams plays an important role in contemporary optics. In this work, we introduce a method of abruptly auto-focusing multi-focus beam (AAMB) along the optical axis. The simulation results show that the AAMB can flexibly adjust the normalized focusing intensity, focal length, and the number of focus points by controlling different beam parameters. Experimental results show that our proposed method achieved a beam with double equal-intensity focus or three equal-intensity focus during propagation. The AAMB enriches the existing multi-focal beam. In addition, the flexible and controllable focusing properties of the beam may broaden the potential applications.

“…Later on, cylindrically symmetric Airy beams were introduced with unexpected abrupt autofocusing [36,37], known as autofocusing beams or ring-Airy beams [38]. These novel wavepackets and their variations [39][40][41][42], were ideal for various applications like trapping and guiding microparticles [43], phase memory preservation [44], and fabrication of large three-dimensional structures [45]. Recently, Airy beams that carry OAM were investigated.…”

We demonstrate that by seeding an accelerating ring-Airy beam with a finite number of off-axis optical vortices, it transforms into a Tornado wave (ToW) upon propagation. Using numerical simulations, we show that both the spiraling high-intensity lobes and the optical vortices exhibit angular acceleration and follow interwinding braid-like trajectories. Likewise, we study the effect of the number, position, and topological charge of the vortices on the propagation dynamics and reveal the connection between optical vortices and optical tornados.
