Experimental Demonstration of a Terahertz Frequency Reference based on Coherent Population Trapping
Mathieu Collombon, Cyril Chatou, Gaétan Hagel +4
A novel protocol of interrogation based on coherent population trapping in an N-level scheme atomic system leads to dark resonances involving three different photons. An ensemble o…

Phase transfer between three visible lasers for coherent population trapping
Mathieu Collombon, Gaetan Hagel, Cyril Chatou +5
Stringent conditions on the phase relation of multiple photons are a prerequisite for novel protocols of high-resolution coherent spectroscopy. In a recent experiment we have imple…
