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

Figure 11

Sign reversal of the velocity selective optical pumping resonance with light intensity, observed at the transition in cell. Cell temperatures T = 25°C. Laser light intensity: W = 16 mW/cm2 (a) and W = 160 mW/cm2 (b). CO denotes the cross-over resonance for both light intensities.
