The alkali metal cell includes a first member, a second member, a cell internal portion, and an alkali metal raw material. In the first member, a first glass substrate is bonded on a second surface of a first substrate where a first opening part is formed. In the second member, a second glass substrate is bonded to a fourth surface of a second substrate where a second opening part is formed. The cell internal portion is formed by the first opening part and the second opening part by bonding the first surface to the third surface. The alkali metal raw material is enclosed by the cell internal portion.

摘要： A method for reducing or eliminating clock bias in an atomic clock is provided. The method comprises cooling a population of atoms collected in the atomic clock using a laser locked at a predetermined frequency, turning off the laser, performing atomic clock spectroscopy, turning on the laser after the atomic clock spectroscopy, and relocking the frequency of the laser to an external reference cell. The population of atoms that are in each of two ground hyperfine levels is then probed using laser light that is on or near-resonant with a selected atomic transition.

摘要： The invention relates to an oscillator consisting of a nanopillar (3) and a means (12) for feeding a power supply current through the nanopillar, the nanopillar comprising at least one pattern (4) including first and second layers (6, 10) made of a ferromagnetic material, which are separated from each other by an intermediate layer (8) made of a non-magnetic material. Each of the first and second ferromagnetic layers is prepared such that the remanent magnetic configuration thereof corresponds to a vortex configuration, and such that the polarity of the vortex core of the first layer is opposite the polarity of the vortex core of the second layer. The intermediate layer is suitable for enabling repellent magnetic coupling between the two vortices of the first and second layers for zero strength of the power supply current and zero amplitude of the outer magnetic field.

摘要： The invention relates to a device for an atomic clock, including: a laser source (102) that generates a laser beam; a splitter (101) that makes it possible to divert and allow a portion of the laser beam to pass therethrough in accordance with a predefined percentage; a quarter-wave plate (105) that modifies the linear polarization of the laser beam into circular polarization and vice versa; a gas cell arranged on the circular polarization laser beam; a mirror (107) sending the laser beam back toward the gas cell (106); and a first photodetector (108a). The splitter (101) is arranged between the laser source (102) and the mirror (107), the quarter-wave plate (105) is arranged between the splitter (101) and the mirror (107), the gas cell (106) is arranged between the quarter-wave plate (105) and the mirror (107) such that the polarization of the beam emitted by the laser source (102) via the splitter (101) and incident on the quarter-wave plate (105) is linear along the first angle and modified by the quarter-wave plate (105) into circular polarization, and the circular polarization of the beam reflected by the mirror (107) and passing through the gas cell (106) a second time is modified into linear polarization along the second angle by the quarter-wave plate (105), the splitter (101) routing a portion of the retroreflected beam to the first photodetector (108a). The device also comprises a polarizer (103) arranged between the laser beam outlet and the splitter in order to protect the laser source from the retroreflections emitted by different optical elements constituting the device.
