Abstract

We study, via wave-optics simulations, the behavior of spatiotemporal (ST) Bessel–Gauss beams in atmospheric turbulence. ST Bessel-Gauss beams are a type of space-time-coupled light field that carries a ST optical vortex: a phase vortex coupling space and time. We provide a brief theoretical discussion of ST Bessel-Gauss beams before simulating their propagation through atmospheric turbulence of varying strengths. We examine the average irradiances (space-time profiles) and mutual coherence functions and compare/contrast those quantities to the free-space results. We conclude with a brief discussion of future work.
