Abstract

We study the effects of spatial coupling in the noise properties of microchip lasers. We demonstrate that the synchronization phenomena commonly observed in spatially coupled unstable laser applies to the quantum-noise-driven dynamics in steady-state stable laser; this allows us to predict a new method of the generation of twin laser beams. We derive simple analytical expressions for the synchronization-induced noise reduction phenomena. We observe a compete suppression of the dominant relaxation oscillations peaks in the intensity difference noise spectrum, as well as photon statistics approaching the standard quantum limit.
