Frontiers in Optics, 2005
An optical vortex may exhibit a hallmark attributed to viscosity in classical fluids: solid-body rotation near the vortex core. This effect, attributed to spatial coherence properties, may be extended beyond optics to other wave systems. Non-quantized circulation results.

OPTICAL VORTEX INTERACTION IN LASERS
International Journal of Bifurcation and Chaos, 1994The Maxwell-Bloch equations describing the transverse modes of a large aspect ratio homogeneously broadened single-longitudinal-mode laser are solved numerically. The solutions are visualized by color-coding the intensity and phase of the transverse electric field at each time step and a video showing the detailed time evolution has been made.

Interferometric optical vortex array generator
Applied Optics, 2007Two new interferometric configurations for optical vortex array generation are presented. These interferometers are different from the conventional interferometers in that they are capable of producing a large number of isolated zeros of intensity, and all of them contain optical vortices. Simulation and theory for optical vortex array generation using

Optical processing with vortex-producing lenses
Applied Optics, 2003We discuss two types of optical processing using vortex-producing angular phase plates. In the most common spatial-filtering operation, an input object is Fourier transformed (either by Fraunhofer diffraction or with a lens system). The Fourier transform is then multiplied by an angular phase pattern, and the product is again Fourier transformed.

Optical Vortex Beams and Optical Vortices
Laser & Optoelectronics Progress, 2008The basic principle, generation,transformation and application of optical vortex beams and optical vortices are briefly summarized, as well as their progress. A brief outlook about the future study and applications of optical vortex beams and optical vortices is discussed.

We describe a phenomenon of nonlinear optics that occurs in the framework of transverse effects and optical vortices in lasers. We find that in a class-B laser vortices can never be at rest, but move, starting from an initial symmetry breaking of the direction of motion, continuously.
