Coherent Population Trapping Resonances in Cs Atomic Vapor Layers of Micrometric Thickness
Figure 12
Sign reversal of the velocity selective optical pumping resonance with light intensity, observed for the transition, in cell (). Atomic source temperature T = 49°C. Light intensity: W = 10 mW/cm2 (a) and W = 102 mW/cm2 (b).
