Special Seminar: Absolute Measurement of a THz Transition Frequency Referenced to a Magnetic Dipolar Transition in Ca+ ion

Special Seminar: Absolute Measurement of a THz Transition Frequency Referenced to a Magnetic Dipolar Transition in Ca+ ion
A three-photon Coherent Population Trapping is observed by the dark line it induces on the laser induced fluorescence of a laser-cooled Ca+ ion cloud. This dark line is referenced to a magnetic dipolar transition at 1.8 THz, between two fine-structure sub-state of a metastable state. We explore the performance of such a system for frequency metrology in the THz domain. [more]
