Description
Optical Raman excitation is used to investigate the ground-state clock transition in laser cooled Rb atoms. The initial state preparation in a Ramsey-type scheme is achieved by coherent population trapping whereas the second pulse is a Raman π/2 pulse allowing the evolution of the coherence to be mapped back onto the bare atomic states. This allows for a significant increase in detected signal compared with a conventional CPT detection scheme.
