Double-resonance spectroscopy in Rubidium vapour-cells for high performance and miniature atomic clocks
Résumé |
We report our studies on using microwave-optical double-resonance
(DR) spectroscopy for a high-performance Rb vapour-cell atomic
clock in view of future industrial applications. The clock physics
package is very compact with a total volume of only 0.8 dm3. It
contains a recently in-house developed magnetron-type cavity and a
Rb vapour cell. A homed-made frequency-stabilized laser system with
an integrated acousto-optical-modulator (AOM) – for switching and
controlling the light output power– is used as an optical source in
a laser head (LH). The LH has the overall volume of 2.5 dm3
including the laser diode, optical elements, AOM and electronics.
In our Rb atomic clock two schemes of continuous-wave DR and
Ramsey-DR schemes are used, where the latter one strongly reduces
the light-shift effect by separation of the interaction of light
and microwave. Applications of the DR clock approach to more
radically miniaturized atomic clocks are discussed. |
