CLOCK ON OPTICAL GRID AND METHOD OF CORRECTING MAGNETIC FIELD FOR CLOCK ON OPTICAL GRID Russian patent published in 2025 - IPC G04F5/14 

FIELD: physics.

SUBSTANCE: invention relates to high-precision meters of time characteristics, to atomic clocks, namely to clocks on an optical lattice and their structural elements. Optical lattice clock comprises a population of atoms held in the optical lattice; moving means for moving the population of atoms held in the optical lattice into the clock transition space; magnetic field correction coil in three axes, optical system containing laser radiation source, laser radiation receiver and laser spectrometer, serving to excite a clock transition in a population of atoms in an optical lattice, in a plurality of places in a correction space, which includes a clock transition space and a size larger than the clock transition space, and to obtain distribution of clock transition frequencies in correction space; and correcting means for magnetic field correction of magnetic field correction coil in three axes depending on frequency distribution.

EFFECT: increased accuracy at reduction of dimensions.
