摘要： The present invention provides a method and apparatus for increasing the intensity of coherent population trapping (CPT) resonances, used in atomic clocks and magnetometers, by pumping the atoms with light of alternating polarization. Pumping with such light, characterized by a photon spin vector that alternates in direction at a hyperfine frequency of the atoms at the location of the atoms, is referred to as push-pull pumping. In one embodiment of the system of the present invention, alkali-metal vapor is pumped with alternating circular-polarization D 1 laser light that is intensity modulated at appropriate resonance frequencies, thereby exciting CPT resonances, which can be observed as increase in the mean transmittanee of the alkali-metal vapor. These resonances are substantially enhanced due to an, optically-induced concentration of atoms in the resonant energy sublevels.

摘要： The production of optical frequency reference signals by means of laser diodes and atomic transition of a diluted gas, e.g. krypton isotope 84, is known. However to do this a frequency which does not lie within the ITU table of frequency allocation is produced. In order to produce a frequency reference signal of a desired frequency, a signal is produced by a second laser diode and superimposed with the first frequency reference signal to produce a differential frequency in the microwave range. A control signal derived from the differential frequency regulates the second injection laser diode with the precision of atomic krypton isotope transition.

摘要： A miniature atomic frequency standard (1) utilizes a tubular vapor cell (7, 75) extending transversely through a TE210 microwave cavity (15, 77). In one embodiment of the invention, the vapor cell (7) is heated directly by electric heaters (57) secured to ends (43, 49) of the tubular vapor cell (7) which extend outside the microwave cavity (15). The vapor cell (7) is insulated by thermal insulation (59, 61) inside the microwave cavity and between the microwave cavity and a magnetic shield (19). In another embodiment of the invention, the entire microwave cavity (77) is heated which eliminates the need for thermal insulation inside the cavity and thus it can be made smaller, but additional thermal insulation (87) is provided between the microwave cavity (77) and the magnetic shield (85). Preferably, the C-field coil (89) is wound on the thermal insulation (87) just inside the magnetic shield (85) to reduce heat loss by conduction. A laser diode (27) outside the magnetic shield (19, 85) transmits light to the vapor cell (7, 75) through an optic fiber (35) without need for a collimating lens, and a photodiode (51) with an integral lens (53) is used as the detector (47).

摘要： Module laser (10) contenant une diode laser (11) asservie en fréquence à l'aide de moyens d'asservissement (40) comportant une cellule de rubidium (41) et un détecteur optique (42), ainsi que des moyens de contrôle (43) du courant d'injection et/ou de la température de la diode laser. Un faisceau lumineux d'asservissement (18) est conduit au moyen d'une fibre optique multimode (14) vers la cellule de rubidium.
Le détecteur optique (42) mesure l'intensité du faisceau lumineux transmis par la cellule de rubidium et fournit un signal utilisé par les moyens de contrôle (43) pour régler le courant d'injection et/ou la température de la diode laser (11), de manière à stabiliser la fréquence de la lumière (16) émise.
La fibre optique (14) est couplée au module laser (10) de manière à récolter une partie de la lumière (16, 21) émise par la face avant de la diode laser (10) et réfléchie par la lentille (12) devant la diode laser. L'ensemble diode laser et lentille est contrôlé thermiquement.
Avantages: Réduction du feed-back dans la diode laser. Réduction de la puissance fournie à la diode laser. Simplification du dispositif d'asservissement.
Applications: interférométrie, étalons atomiques de fréquence, spectroscopie, transmission d'informations sur fibre optique.
