Abstract

The effect of temporal coherence on the phenomena of self-oscillation in photorefractive materials is analyzed using multilongitudinal-mode argon-ion and helium–neon lasers. Observations demonstrate that self-oscillation is possible when the mirror–crystal separation is large compared to the laser coherence length. The observations are shown to agree with predictions based on the recurrence in the temporal coherence of a multilongitudinal-mode laser.
