Summary: This paper successfully generates high-quality white-light Airy beams and Bessel beams using a deformable mirror by modulating the incident LED beam with tunable wavefronts. The generated white-light non-diffraction beams are not affected by chromatic dispersion during propagation, and the generation of white-light Bessel beams has higher requirements for spatial coherence.

Summary: We report a class of nondiffracting solutions to the paraxial wave equation perturbed by a harmonic potential. These solutions allow light to accelerate along an arbitrary trajectory centered on an elliptic or circular orbit in a (2+1)D configuration, while maintaining their phase and polarization structures during propagation. We name these oscillating wave packets as pendulum-type beams.

Summary: This paper provides an analytical theory for Gaussian modulated Airy (gAiry) acoustic beams and reveals that gAiry beams inherit the advantages of standard Airy beams. Numerical calculations and finite element simulations show that side lobes are reduced in gAiry fields generated by sources of limited apertures, and bilateral focusing using a pair of beams improves field features compared to focused Airy fields. The theories and observations presented in this paper can contribute to the deployment of gAiry beams in applications.

Summary: This study focuses on the transmission of Airy-Gaussian beams in photorefractive medium, finding that solitons are influenced by the photorefractive effect during transmission. The characteristic parameters of solitons can be controlled and adjusted by the Levy index and photorefractive coefficient.

Summary: Using angular spectral representation, this study demonstrates a generalized approach for generating high-dimensional elliptic umbilic and hyperbolic umbilic caustics by phase holograms. The properties of these umbilic beams are investigated via diffraction catastrophe theory and they exhibit unique features such as autofocusing and self-healing. Numerical results and experimental verification show their potential applications in particle manipulation and optical micromachining.

Summary: This study designs autofocusing Airy-like beams based on self-accelerating beams along arbitrary polynomial paths and investigates their evolution in different environments. The results demonstrate that the energy concentration of the autofocusing beam near the focal plane is closely related to its accelerating trajectory, and the spot size in the focal plane varies with the acceleration trajectory. Moreover, the influence of turbulence on different beams differs depending on the curvature of the accelerating beam, with beams propagating along paths of smaller curvature showing better resistance against turbulence.

Summary: This work introduces and demonstrates a method for tailoring multi-focus abruptly autofocusing beams in free space. It allows for direct and independent adjustment of the number, positions, and relative intensity of foci by controlling the design of abruptly autofocusing beams. The study also explores the relationship between the size of the light field and the characteristics of focus. By utilizing the double-phase hologram method, the required complex field is generated using a phase-only spatial light modulator in experiments, providing flexible control over the characteristics of foci and expanding potential applications of autofocusing beams.

Summary: The study focuses on the dynamics of electron beams that are self-accelerating in free space and in the presence of an additional magnetic field, with specific attention to Airy beams and power-law trajectories. It explores the interaction between beam self-acceleration and circular motion caused by the magnetic field. Using an integral representation, closed-form solutions for the electron wave function are found, along with asymptotic formulas for beam trajectories, and ray optics is useful for interpreting beam dynamics. The results are in excellent agreement with direct numerical simulations.

Summary: Based on the fractional Schro?dinger equation, the evolution of AiG beams under Gaussian potential was studied using the split-step Fourier method. The study found that beam splitting only occurs when the beam is incident vertically, and periodic evolution can be achieved by assigning appropriate barrier parameters values. The critical barrier height increases with the larger Le?vy index, while total reflection is easier to achieve in Gaussian barriers compared to Gaussian wells.

Summary: This article presents the generation of Circle Olver Beams (COBs) by modulating a new type of Olver beam both numerically and experimentally. The zeroth order COB is the circle Airy beam. The COBs exhibit self-focusing behavior with inward and outward accelerations, with odd order COBs displaying auto-defocusing and even order COBs focusing more sharply. The study also investigates the impact of decay factor and scaling factor on the beams' focusing properties using parity mode, and confirms the self-healing property of COBs. Practical applications such as particle manipulation and laser processing are explored using the COBs.
