High-velocity dark states in velocity-selective coherent population trapping

We have observed long-lived dark states in velocity-selective coherent population trapping (VSCPT) in a one-dimensional lin-angle-lin configuration with metastable He atoms using the {ital J}=1{r_arrow}1 transition at {lambda}=1.083 {mu}m. These states are characterized by two peaks in the atomic mo...
