Abstract

Airy beams, celebrated for their self-acceleration, diffraction-free propagation, and self-healing properties, have garnered significant interest in optics and photonics, with applications spanning ultrafast optics, laser processing, nonlinear optics, and optical communications. Recent research primarily aims at independent control of Airy beams in both spatial and spatiotemporal domains. In a pioneering approach, we have successfully generated and controlled a spatiotemporal coupled (STc) Airy-Airy wavepacket, achieving its rotation while preserving vertical distribution in the spatiotemporal domain. Furthermore, we have investigated the self-acceleration and self-healing properties of the STc Airy-Airy wavepacket in this domain, noting that its dynamically adjustable rotation and spatiotemporal coupling capability provide a novel strategy for managing ultrafast lasers, with potential advancements in optical micromanipulation and time-domain coding communication.
