A Cold-Atom Clock Based on Coherent Population Trapping
نویسندگان
چکیده
A compact cold-atom clock based on coherent population trapping is being developed. The clock aims to ultimately achieve a timing uncertainty of a few nanoseconds per day. Here we present an initial evaluation of the three main systematic frequency shifts – the first-order Doppler shift, the light shift, and the Zeeman shift. Planned steps to reduce the size of these shifts will also be presented.

Light shifts in a pulsed cold-atom coherent-population-trapping clock
Field-grade atomic clocks capable of primary standard performance in compact physics packages would be of significant value in applications ranging from network synchronization to inertial navigation. A coherent-population-trapping clock featuring laser-cooled 87Rb atoms and pulsed Ramsey interrogation is a strong candidate for this technology if the frequency biases can be minimized and contro...

Cesium atomic beam clocks have been the workhorse for many demanding applications in science and technology for the past four decades. Tests of the fundamental laws of physics and the search for minute changes in fundamental constants, the synchronization of telecommunication networks, and realization of the satellite-based global positioning system would not be possible without atomic clocks. ...

A summary of the entire scope of the Kansas State University AMO program is contained in the J. R. Macdonald Laboratory abstract. The present document is limited to a discussion of recent progress in the MOTRIMS projects. MOTRIMS, or magneto optical trap recoil ion momentum spectroscopy, is a methodology originally developed for the study of ion-atom or photon-atom collisions. Following the bas...
متن کاملAtomic clocks and coherent population trapping: Experiments for undergraduate laboratories
We demonstrate how to construct and operate a simple and affordable apparatus for producing coherent effects in atomic vapor and for investigating their applications in time-keeping and magnetometery. The apparatus consists of a vertical cavity surface emitting diode laser directly current-modulated using a tunable microwave oscillator to produce multiple optical fields needed for the observati...
