Squeezed light from conventionally pumped lasers with nonuniform spatial structure
Craig M. Savage, Timothy C. Ralph · Physical Review A · 1992
Spatial variations of the laser mode and pumping rate are incorporated into the theory of conventionally pumped lasers that produce squeezed light. Both a quantum-mechanical theory and a heuristic statistical model are used. While variations in the laser mode are found to have a negligible effect on squeezing, variations in the pumping rate are significant. The maximum attainable squeezing is always reduced compared with the spatially uniform case. However, resonantly enhancing a low-power pump in a Fabry-P\'erot cavity, rather than a ring cavity, may give better squeezing.
