QUANTUM FREQUENCY STANDARD ON GAS CELL Russian patent published in 2012 - IPC H03L7/26 H01S1/06 

FIELD: physics.

SUBSTANCE: device comprises, connected into an automatic frequency control closed ring, a tunable crystal oscillator, a unit for generating exciting and reference signals, a quantum discriminator unit and an automatic frequency control unit, a trigger device; the quantum discriminator unit comprises, on one optical axis, an electrodeless spectral lamp fitted with an inductor - plasma discharge exciter, a gas cell inside a microwave resonator, whose radio-frequency input is connected to the signal output of the unit for generating exciting and reference signals, and a photodetector; the device also has inductor for the electrodeless spectral lamp, a unit for generating an induction signal, which is in form of series-connected frequency multiplier with nominal frequency of the output signal in the range from 90 MHz to 300 MHz and a controlled power amplifier.

EFFECT: design of a more reliable and cheaper quantum frequency standard on a gas cell with reduced fluctuation of optical pumping light intensity.
