Abstract
A magneto-optical trap apparatus includes a vacuum vessel for encapsulating an atom to be trapped, an anti-Helmholtz coil for applying a magnetic field to an inside of the vacuum vessel, a laser device for generating a laser beam, and an irradiation device for irradiating the generated laser beam from a plurality of directions. The laser beam includes a first laser beam detuned from a first resonance frequency when the atom transits from a total angular momentum quantum number F in a ground state to a total angular momentum quantum number F'=F+1 in an excited state, and a second laser beam detuned from a second resonance frequency when the atom transits from the total angular momentum quantum number F in the ground state to a total angular momentum quantum number F′=F−1 in the excited state, among transitions from J=0 in a ground state to J′=1 in an excited state.
