QUANTUM FREQUENCY STANDARD Russian patent published in 2023 - IPC H03L7/26 H01S1/06 

FIELD: electromagnetic technology.

SUBSTANCE: invention relates to the frequency stabilization technology. The invention contains the first magnetic screen, in the center of it on the optical axis there is a pump lamp, a filter cell, an absorption chamber with a resonator and a photodetector connected to a low frequency amplifier ω₁, a resonator with an absorption chamber in the center of the first solenoid, the amplifier is connected to a phase detector that is connected to the frequency generator ω₁, the phase detector is connected to a quartz generator, the connected frequency generator ω₁, the quartz generator is connected to a frequency multiplier connected to the first resonator. A second magnetic screen is placed near the first one, in the center of it on the optical axis there is a pump lamp, a filter cell, an absorption chamber with a resonator and a photodetector connected to a low frequency amplifier ω₂, a resonator with an absorption chamber in the center of the second solenoid, the amplifier is connected to the phase detector connected to a low frequency generator ω₂, the phase detector is connected to a quartz generator, connected to a frequency generator ω₂, the resonator is connected to a frequency multiplier.

EFFECT: reducing the effect of changing the direction of the external magnetic field on its resonant frequency.
