Low-intensity degenerate four-wave mixing at the cesium D1 resonance in thin cells.
We observed low-intensity cw degenerate four-wave mixing at the D1 resonance in a 10-microm-thick cesium-vapor cell. Normal population depletion caused by optical pumping is alleviated by frequent atom-wall collisions. The reflectivity at the D1 resonance is approximately equal in magnitude to that observed at the D2 cycling transition under similar conditions.
