Laser-free slow atom source
A slow atom source, which does not rely on lasers, has been developed and characterized. The device, acting as an atomic low-pass velocity filter, utilizes permanent magnets to passively select the slow atoms present in a thermal atomic beam. Slow atoms are guided along a curved, conduction-limited tube by an octupole magnetic field, while fast atoms, unable to follow the curved trajectory, str...
متن کاملLaser controlled atom source for optical clocks
Precision timekeeping has been a driving force in innovation, from defining agricultural seasons to atomic clocks enabling satellite navigation, broadband communication and high-speed trading. We are on the verge of a revolution in atomic timekeeping, where optical clocks promise an over thousand-fold improvement in stability and accuracy. However, complex setups and sensitivity to thermal radi...
متن کاملDual-wavelength laser source for onboard atom interferometry.
We present a compact and stable dual-wavelength laser source for onboard atom interferometry with two different atomic species. It is based on frequency-doubled telecom lasers locked on a femtosecond optical frequency comb. We take advantage of the maturity of fiber telecom technology to reduce the number of free-space optical components, which are intrinsically less stable, and to make the set...
متن کاملMultiple species atom source for laser-cooling experiments
We describe the design of a single beam, multiple species atom source in which the flux of any component can be separately adjusted. Using this design we have developed a Na–Li atom source for ultracold atom experiments. The fluxes of lithium and sodium are independently tunable, allowing operation as a single Na or Li source as well as a double source with equal atomic fluxes in each component...
متن کاملTheory of slow-atom collisions.
A general theory of slow-atom collisions is presented with special emphasis on the effects of nuclear statistics and atomic fine and/or hyperfine structures. Symmetry properties of the collision complex and correlations between the molecular states and the separated-atom states are carefully examined. The frame transformations between various angular momentum coupling schemes are derived, which...
