Scattering of partially coherent vortex beam by rough surface in atmospheric turbulence.
Optics Express, 2022 A double-passage propagation model of partially coherent Laguerre-Gaussian (LG) vortex beams with orbital angular momentum (OAM) modes in turbulent atmosphere after scattering from Gaussian rough surfaces was formulated.

Partially coherent stable and spiral beams [PDF]
Journal of the Optical Society of America A, 2013 Stable and spiral coherent beams, which do not change the form of their intensity distribution apart from possible scaling and rotation during propagation and therefore possess self-healing properties, are widely applied in science and technology. On the other hand, it has been found that partially coherent light often provides better output than ...

Nonlocal incoherent solitons [PDF]
, 2004 We investigate the propagation of partially coherent beams in spatially nonlocal nonlinear media with a logarithmic type of nonlinearity. We derive analytical formulas for the evolution of the beam parameters and conditions for the formation of nonlocal ...
