Photorefractive two-beam coupling with reduced spatiotemporal coherence.
Photorefractive two-beam coupling with reduced spatiotemporal coherence is investigated both theoretically and experimentally. Limited spatiotemporal coherence results in spatially limited grating regions. Theoretical predictions of the beam-coupling behavior in two symmetries are supported by experimental results.
