Spatial quantum effects with continuous-wave laser beams

Bachor, Hans; Delaubert, V; Harb, Charles; Hsu, Magnus; Lam, Ping Koy; Fabre, Claude; Treps, Nicolas


The application of quantum optics to spatial measurements with continuous-wave laser beams is discussed. In particular, we summarize the work on measuring small displacements and tilt. We present the required theoretical multi-mode model and discuss how it applies to split detectors and spatial homodyne detectors. We show how spatial measurements can be improved using squeezed light. Finally, we present a demonstration of improved spatial homodyne measurements using squeezed light in a higher...[Show more]
