Characterization of coherent population-trapping resonances as atomic frequency references
A low-cost, potentially compact and robust microwave frequency reference can be constructed by use of vertical-cavity surface-emitting lasers and coherent population-trapping resonances in Cs vapor cells. Fractional frequency instabilities of 2 3 10211/At/s have been achieved with a minimum of 7 3 10213 at t 5 1000 s. The performance of this device as a function of external parameters such as l...
متن کاملPerformance of a prototype atomic clock based on lin‖ lin coherent population trapping resonances in Rb atomic vapor
We report on the performance of the first table-top prototype atomic clock based on coherent population trapping (CPT) resonances with parallel linearly polarized optical fields (lin lin configuration). Our apparatus uses a vertical-cavity surface-emitting laser (VCSEL) tuned to the D1 line of Rb with the current modulation at the Rb hyperfine frequency. We demonstrate cancellation of the first...
متن کاملInfluence of coherent Raman scattering on coherent population trapping in atomic sodium vapor
We study how coherent Stokes and anti-Stokes Raman scattering influence coherent population trapping. In an experiment using an atomic sodium vapor cell we observe induced transparency, induced absorption, and gain features, all of subnatural linewidth. The electromagnetically induced resonance is a peak or a dip depending on which side of the optical transition the fields are tuned to, and thu...
متن کاملShape of the Coherent Population Trapping Resonances Registered in Fluorescence
There has been permanent interest in investigations of new magnetic sensors and their various applications (Edelstein, 2007). Last years there is a rapid progress in development of magneto-optical sensors because of their sensitivity and potential for miniaturization. Magnetometers, based on magneto-optical sensors have high sensitivity comparable to, or even surpassing this of the SQUIDs (Supe...
متن کاملCoherent trapping of atomic populations.
It is often desirable in laser spectroscopy and isotope separation to extract as much as possible of an atomic or molecular population that is distributed among a number of ground-state sublevels and low-lying metastable levels. We describe a form of coherent trapping that occurs when multiple resonant laser beams are used to couple the various ground states to a common upper level. This effect...
