Raymer, M G

A number of advances were made in improving the understanding of multimode dye laser dynamics. The source of mode-intensity fluctuations in a three-mirror, multimode dye laser has been identified in the typical operating regime well above threshold. It was found experimentally that deterministic four-wave mixing interactions are the underlying cause. We have also made new theoretical studies concerning the regime just above threshold and predicted that the mode fluctuations will be dominated by quantum noise in this regime. We have constructed a short-cavity dye laser in order to enhance this quantum effect, and have made measurements of the turn-on time statistics of individual modes. Effects of coherent, four-wave mixing interactions on these statistics have been identified. 19 refs.
