Title:
PHYSICAL PACKAGE FOR OPTICAL LATTICE CLOCK
Document Type and Number:
WIPO Patent Application WO/2021/200909
Kind Code:
A1
Abstract:
Provided is a physical package for an optical lattice clock which has a structure that makes it possible to achieve reduction in size or transportation. A physical package (12) is provided with: a Zeeman slower (44) with a partial MOT and a partial MOT device (48) which constitute an MOT device; an optical chamber (46) which constitutes an optical lattice formation part; and a vacuum chamber (20) which surrounds these components and has a substantially cylindrical shape. The MOT device is arranged along the beam axis of an atomic beam (42) and traps an atom cluster. The optical lattice formation part uses optical lattice light that enters therein to form an optical lattice in a cavity, confines the atom cluster trapped by the MOT device in the optical lattice, and transfers, along the X-axis which is a movement axis perpendicular to the beam axis, the atom cluster to a clock transition space (52) which facilitates clock transition. The central axis of the cylinder of the main body (22) of the vacuum chamber (20) passes through the clock transition space (52), and is set to be substantially parallel with the beam axis.
