A simple method for stabilizing the laser frequency to an atomic transition is described. It makes use of the frequency shift caused by the Doppler effect. With this method the frequency of a dye laser can be kept tuned to an atomic resonance line within 10% of the linewidth for periods of...
We have proved experimentally that the frequency shift formula of AC Zeeman effect presented by us is correct. In a 87Rb atomic frequency standard we add a new microwave field which causes the frequency shift of O-O transition frequency of 87Rb atomic ground state. This frequency shift as a...
The decoherence of those ions, with transition frequencies outside the bandwidth of the π pulse, cannot be recovered by the DD sequences, thus leading to an efficiency loss. ηspin is also related to the inhomogeneity of the RF field generated by the coils, because the thickness of the ...
A physics package for rubidium atomic frequency standard with a short-term stability of 2.4 × 1013 τ1/2 In this article, a new type of physics package with high signal to noise ratio for a rubidium atomic frequency standard is reported. To enhance the clock transition signal, a slotted tu...
The signal is stabilized onto the atomic transition frequency by tuning finely a voltage-controlled phase shifter implemented in the 2.298 GHz HBAR-oscillator loop, preventing the need for a high-power-consuming direct digital synthesis. The short-term fractional frequency stability of the free-...
The spatial resolution of ponderomotive spectroscopy is orders of magnitude better than the transition frequency would suggest, promising single-site addressability in dense particle arrays for quantum computing applications. 展开 关键词: Physics - Atomic Physics ...
capable of generating a range of transitions around the expected transition point. When they fired it at the target , one particular light stream matched the nuclear transition frequency. Although the system needs optimization , Zhang says, "It's the first demonstration that all the components of...
