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…
Symmetry breaking in linear multipole traps
Jofre Pedregosa-Gutierrez, Caroline Champenois, Marius Kamsap +3
Radiofrequency multipole traps have been used for some decades in cold collision experiments, and are gaining interest for precision spectroscopy due to their low mi-cromotion cont…
Noise characterization of an Optical Frequency Comb using Offline Cross-Correlation
Ramin Khayatzadeh, Mathieu Collombon, Didier Guyomarc'h +6
Using an offline cross-correlation technique, we have analyzed the noise behavior of a new type of optical frequency comb (OFC), which is carrier envelope offset (CEO) free by conf…
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…
Some aspects of simulation and realization of an optical reference cavity
Didier Guyomarc'H, Gaëtan Hagel, Cédric Zumsteg +1
The interrogation of an ultra-narrow clock transition of a single trapped ion for optical frequency metrology requires a laser stabilized to a couple of Hz per second with a linewi…
