PHYSICAL PART FOR CLOCK ON OPTICAL ARRAY Russian patent published in 2024 - IPC G04F5/14 

FIELD: clocks and other time meters.

SUBSTANCE: physical part (12) comprises: Zeeman retarder (44) with a portion which is a part of a magnetooptical trap, and device (48) which is a part of the MOT, which form a magnetooptical trap (MOT); optical chamber (46) forming an optical array forming section; and vacuum chamber (20) enclosing said components and made substantially in the form of a cylinder. MOT device is located along the axis of atomic beam (42) and catches a group of atoms. Optical grating formation section uses optical grating light entering it to form an optical grating in the resonator, holding a group of atoms trapped by the MOT device, in the optical lattice and moving along the axis X, which is the axis of movement perpendicular to the axis of the beam, said group of atoms into the clock transition space (52), which facilitates the occurrence of the clock transition. Central axis of the cylinder of main housing (22) of vacuum chamber (20) passes through space (52) of the clock transition and is set so that it is substantially parallel to the axis of the beam.

EFFECT: disclosed is a physical part for a clock on an optical lattice, the design of which enables to reduce the size and the possibility of transportation.
