Coherent Population Trapping Resonances in Cs Atomic Vapor Layers of Micrometric Thickness

Figure 3

CPT dark resonance profile with laser power density enhancement observed at the set of transitions: (a) conventional cell with and atomic source temperature T = 22°C; (b) thin cell with at T = 34°C. In both cells, no resonance sign change is observed.
