QUANTUM DISCRIMINATOR Russian patent published in 1994 - IPC

FIELD: quantum radiophysics. SUBSTANCE: quantum discriminator has source of optical pumping, cell-filter, photodetector and thermostated SHF resonator on wave type H₁₁₁. Three translucent coaxial sealed cylindrical spaces are located inside SHF resonator. They are inserted into each other. Central space is source of optical pumping. Middle space is optical filter and peripheral one is absorption cell. Discriminator provides for close to 100% use of radiation of source for pumping of atoms Rb₈₇ in absorption cell. EFFECT: increased stability of frequency with simultaneous decrease of dimensions of quantum discriminator. 1 dwg
