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…
Coherent internal state transfer by three-photon STIRAP-like scheme for many-atom samples
Marius Romuald Kamsap, Thierry Blanchard Ekogo, Jofre Pedregosa-Gutierrez +5
A STIRAP-like scheme is proposed to exploit a three-photon resonance taking place in alkaline-earth-metal ions. This scheme is designed for state transfer between the two fine stru…
Two-step Doppler cooling of a three-level ladder system with an intermediate metastable level
Caroline Champenois, Gaetan Hagel, Martina Knoop +4
Doppler laser cooling of a three-level ladder system using two near-resonant laser fields is analyzed in the case of the intermediate level being metastable while the upper level i…
Terahertz frequency standard based on three-photon coherent population trapping
Caroline Champenois, Gaetan Hagel, Marie Houssin +3
A scheme for a THz frequency standard based on three-photon coherent population trapping in stored ions is proposed. Assuming the propagation directions of the three lasers obey th…
