ATOM COOLING DEVICE, IN PARTICULAR AN ATOM TRAP, AND METHOD FOR COOLING OR TRAPPING ATOMS

摘要

The invention relates to an atom cooling device (10), in particular an atom trap, comprising: (a) a laser system (12) for emitting a laser beam (14); (b) a magnetic quadrupole-field generator (16); and (c) a light reflector, which is arranged to reflect the laser beam (14) such that a trap volume (26) is formed, wherein the light reflector is a Fresnel reflector (20).
