Document Type and Number:
WIPO Patent Application WO/2024/004487
Kind Code:
A1
Abstract:
According to the present invention, in a first area that captures atoms in a first state by means of first light and a magnetic field, atoms are optically pumped into a second state and thereby captured by magnetic force. The atoms in the second state captured in the first area are moved from the first area to a second area by means of gravity or the radiation pressure of second light. In the second area, the second light is radiated at the atoms in the second state, and the atoms in the second state are thereby cooled. The atoms are optically pumped into a third state that is insensitive to magnetic fields and thereby released from a magnetic trap and supplied to a downstream device by means of a moving optical lattice or an optical dipole guide.
