| 摘要 |
The present invention improves accuracy by increasing the number of atoms engaged in a clock transitions in an optical lattice clock. An exemplary optical lattice clock (100) of an embodiment comprises an optical waveguide (10), an optical path (20), a laser light source (30), and a laser cooler (40). The optical path has a hollow pathway (14) that extends from a first end (16) to a second end (18) while being surrounded with a tubular wall (12), which is used as a waveguide path. The optical path passes between mirrors (26) and (28) through the pathway (14). The laser light source supplies to the optical path a pair of lattice lasers (L1 and L2) propagating in opposite directions with each other. The laser cooler (40) supplies cooled atoms (50) that have two levels of electronic states associated with a clock transition to the vicinity of the first end (16) of the optical waveguide (10). |
