Abstract
We describe observation and analysis of optical vortex patterns in a u nidirectional ring oscillator with photorefractive nonlinearity. Inclu ding field rotation in the resonator leads to novel structures, includ ing counterrotating rings of optical vortices with opposite helicity. A modal analysis is used to explain the observed patterns.
