  • Hyperfine filter for the resonance lines of caesium and rubidium
    Patent number: 3938877
    Abstract: A hyperfine filter for the resonance lines of alkali metals, as caesium and rubidium, comprising:A cell transparent to the light rays and which contains vapours of the alkali metal to be filtered;Means for generating a magnetic field, into which is placed said cell;A lamp of said metal, means to direct the light beam emitted from the lamp to hit said cell where only one of the two orthogonal components of circular polarization is absorbed;A circular analyzer provided to separe one of the hyperfine component of the light beam emerging from said cell from the other; andAn interference filter to select the particular resonance line which is desired to be used.
