Beam positioning stability analysis on large laser facilities
High Power Laser Science and Engineering, 2013 Beam positioning stability in a laser-driven inertial confinement fusion (ICF) facility is a vital problem that needs to be fixed. Each laser beam in the facility is transmitted in lots of optics for hundreds of meters, and then targeted in a micro-sized

Experimental investigation in Airy transform of Gaussian beams with optical vortex
Results in Physics, 2021 The Airy transform was first introduced for a Gaussian beam, and the output beam is an Airy beam. When the Gaussian beam is extended to the Gaussian beam with optical vortex, what kind of output beam will be achieved by executing the Airy transformation.

Steering the propagation of finite-energy Airy beam by spatial phase modulation
Results in Physics, 2019 The effect of spatial phase modulation on the propagation of finite-energy Airy beam (FEAB) is investigated. A sinusoidal phase is introduced on a FEAB and the propagation behavior is analyzed in Kerr medium by numerical simulation.

Dynamic Control of Circular Airy Beams With Linear Optical Potentials
IEEE Photonics Journal, 2012 We investigate the propagation dynamics of radially symmetric, circular Airy beams through a medium having linear optical potentials. On the basis of analytic expressions and numerical calculations, we show that “off-axis” autofocusing can ...

Journal of Marine Science and Engineering, 2021 In this paper, we use two methods to research the propagation characteristics of a Hypergeometric-Gaussian (HyGG) vortex beam under oceanic turbulence. One is numerical calculation based on the Rytov approximation theory, where the theoretical detection ...
