Abstract

PURPOSE:To improve the pumping radiation intensity and Q factor of the microwave of an atomic frequency standard by employing a rubidium lamp as a pumping radiation source constituting an atomic frequency standard as well as setting the lamp inside a cut-off waveguide. CONSTITUTION:At the opening of a cavity resonator 31 containing a cell 4, solar cell 8 and microwave antenna 7, a cut-off waveguide 32 is provided, inside which a pumping radiation source using a rubidium lamp 1 is set and oscillated by an exciting coil 2. Then, as usual, a series circuit comprising an amplifier having a phase synchronous detector, a low-frequency oscillator and a frequency synthesizer is connected between the solar cell 8 and the antenna 7, and a voltage-controlled crystal oscillator is provied between the amplifier and the synthesizer. Because the lamp 1 is set inside the waveguide 32 so as to be in one body with the resonator 31, the atomic frequency standard is made more compact, and the radiation intensity and Q factor are improved as well as the characteristics are stabilized.
