The lattice has regular sites that are less than a wavelength … Webb11 dec. 2024 · The optical tweezer clock offers an intriguing compromise between the single-ion and lattice approaches. An optical tweezer is a tightly focused laser beam that can pull atoms (or other small objects) to its narrowest point.
Webb3 apr. 2024 · In this work, we combine these two technologies using flip-chip bonding and demonstrate an architecture for packaging a compact strontium atomic clock. Our planar design includes twelve beams in two co-aligned magneto-optical traps. These beams are directed above the chip to intersect at a central location with diameters > 1 mm. As the nation’s civilian timekeeping agency, NIST is always working to improve atomic clocks and develop potential future time standards, including lattice clocks. In 2000, Jun Ye, Andrew Ludlow and colleagues started working with strontium in efforts that would lead to the first JILA optical lattice clock, reported in … Visa mer Among their many uses, laser beams can trap matter such as atoms and molecules.
