ZEEMAN ATOMIC BEAM RETARDER Russian patent published in 2016 - IPC H05H3/02 

FIELD: electronics.

SUBSTANCE: invention relates to quantum electronics and can be used in atomic beam frequency standard on beams of rubidium or caesium atoms. Zeeman atomic beam retarder contains an atomic beam, solenoid intended for generating an inhomogeneous magnetic field, acting on an atomic beam passing through it, as well as optically-connected source of back optical radiation and acousto-optical modulator designed to generate direct and displaced beams, acting on atomic beam passing through solenoid. Apparatus includes an optical separator of atomic beam, intended for deflection of low-speed part of atomic beam, generated by atomic beam source, and formation therefrom of an additional deflected collimated atomic beam passing through solenoid. Optical separator of atomic beam has a deflecting optical radiation source, intended for deflection of low-speed part of atomic beam, generated by atomic beam source, as well as two sources of cross optical radiation, intended for collimating said deflected part of atomic beam. Result is achieved due to spatial separation of initial atomic beam into high-speed and low-speed parts with help of optical separation of atoms and subsequent application of backward optical effect to selected low-speed part.

EFFECT: technical result is reduction of power consumption and overall dimensions.
