“…(ii) In our experiment, the self-healing optical field with uniform distributed multiple independent optical spots are generated. Although there are multiple spots in other self-healing beams such as Airy beam, Mathieu beam, Weber beam, and Pearcey beams consisting of multiple spots, not all spots can be used in practice applications due to asymmetric and nonuniform pattern [18]. Our scheme works will be helpful in the application of multipoint light manipulation and laser machining.…”

“…Beyond the classical Bessel beam, the self-healing of Airy and its family beams has also been studied [10][11][12][13][14][15][16][17]. Furthermore, the other ingeniously designed structured beams based on fundamental non-diffracting beams [18], such as caustic beam [19], Mathieu beam [20], Weber beam [21], Pearcey beams [22], pillar beam [23], optical ring lattice [24], helico-conical beams [25], can recover the intensity profile of the optical field. Recently, the self-healing of self-rotating beams has been proposed by Niu et al, which can overcome obstacles and regenerate after a characteristic distance [26].…”

Optical self-healing is a repairing phenomenon of a beam in the propagation, as it is perturbed by an opaque object. In this work, we demonstrate experimentally and theoretically that the moiré distributed dual-microlens array enables to generate optical fields with better healing ability to withstand defects than their counterparts of a single microlens array. By utilizing the double parameter scanning method, the self-healing degree of the optical field is significantly affected by both the interval distance and the relative angle of the dual-microlens arrays. The self-healing level is decreased significantly by lengthening the interval between the two microlens array with a small twist angle, while increasing the angle enhances the self-healing degree. Further study manifests the self-healing process with respect to the size and central location of the obstacle. The research results provide a simple and effective method to generate self-healing optical wave fields, which have potential applications including optical communication, assisted imaging technology, and even intense laser physics.

“…In recent times, the emergence of structured light has unlocked access to a range of unique light profiles such as Bessel beams (BB). These beams offer notable advantages such as self-healing optical properties, , carrying orbital angular momentum, possessing an extended depth of focus (DOF), − maintaining intensity profile consistency along their propagation, and thus presenting themselves as promising candidates for exploring novel laser–matter interactions, surface lithography, optical trapping. Among these, the axicon-generated BB stands out, presenting a distance-invariant, self-repairing intensity profile, enhancing the depth of field.…”

Arising from ultrashort laser−matter interactions, laser-induced periodic surface structures (LIPSS) have evolved into promising applications in various fields, such as nanophotonics, solar energy conversion, photodetectors, photocatalysis, and sensing. This study presents the creation of a novel nanotubular arrayed silver (Ag) LIPSS utilizing an axicon-generated femtosecond Bessel beam. A meticulous exploration has unraveled the mechanism behind Bessel beam-induced LIPSS formation, revealing how the modulation of the ablation fluence profile, intertwined with the interaction of photon-induced surface plasmon polariton (SPP) and the incident beam, plays a pivotal role. The influence of the Bessel beam profile and the SPP decay length have been crucial factors in crafting such distinctive nanostructures. The period (Λ) of the fabricated low spatial frequency LIPSS stands estimated at 575 ± 10 nm. The distinct topographical characteristics of Ag nanostructures generated using a Gaussian beam with identical fluence are also presented. Furthermore, these plasmonic nanostructures have exhibited exceptional efficacy and versatility as active substrates for surfaceenhanced Raman scattering (SERS)-based sensing applications. Traces of real-time explosives such as TNT, tetryl, RDX, and HMX with the lowest concentrations ranging from 50 to 500 nM have been successfully detected. The achieved enhancement factors hovered around 10 6 , rendering these substrates highly practical for real-world applications. Moreover, our investigation of the BB ablation process unveiled its promising applications in creating antireflection surfaces. En bloc, this study significantly enhances the knowledge on the unexplored research area of Bessel beam−metal interaction, leading to the formation of exotic nanotubular LIPSS, demonstrating versatile SERS-based sensing applications.

“…Initially, it was thought that the beam self-healing property was affected by its non-diffraction behavior. However, the obtained results in recent years show that the self-healing property of structured light is not limited to non-diffracting beams such as Bessel, Bessel-Gaussian, Pearcey, and Airy; it is reliable for diffracting beams such as Hermite-Gaussian, Ince-Gaussian, Laguerre-Gaussian [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21].…”

‎This paper introduces a new approach to the self-healing quantification of structured light beams‎. ‎The self-healing is quantitatively determined by defining a self-healing degree (SHD) and a similarity function based on comparing the intensity distributions of the perturbed and unperturbed beams‎. ‎In addition‎, ‎the SHD is employed for two other intensity-based methods to compare the methods' performance. The Bessel beams with integer and fractional topological charges are examined numerically to verify the method‎. ‎Further‎, ‎the effect of superposition of the Bessel and mirrored Bessel beams with respect to the x-axis on the self-healing property is investigated‎. ‎The perturbation of the beams is applied using a pair of circular masks as a symmetric perturbation‎. ‎The propagating of perturbed and unperturbed beams is simulated by the angular spectrum method‎. ‎The obtained quantitative results are confirmed by the intuitive results and also the accuracy of the proposed method is similar to the other used methods‎. ‎‎‎On the other hand‎, ‎due to using fewer calculations with respect to them and so is less time-consuming ‎(about 57\% and 67\% reduction in computational time)‎, ‎it can be used as an adequate alternative method‎. ‎‎‎As a result of this method‎, ‎it is shown that the superposition of Bessel beams with their mirrored ones is an effective factor to improve the self-healing property‎, ‎in which the SHD of the superposed beams is more than the Bessel beams for each topological charge‎. ‎It is also shown that using the fractional topological charge beams is another advantageous improvement to increase the SHD‎.
