Creation, doubling and splitting of vortices in intracavity second harmonic generation
Lim, O-K; Boland, B; Saffman, Mark; Krolikowski, Wieslaw
We demonstrate the generation and frequency doubling of unit charge vortices in a linear astigmatic resonator. The topological instability of the double charge harmonic vortices leads to well separated vortex cores that are shown to rotate, and become anisotropic, as the resonator is tuned across resonance.
