SUBMINIATURE QUANTUM FREQUENCY STANDARD AND THE METHOD FOR ARRANGING ITS COMPONENTS Russian patent published in 2022 - IPC H03L7/26 H01S1/06 

FIELD: electrical harmonic signal creation.

SUBSTANCE: inventions relate to means for creating an electrical harmonic signal with a given highly stable frequency. To achieve the effect, a quantum frequency standard is proposed, containing a housing, a quantum discriminator, a quartz oscillator and an electronic control system. The thermal stabilization and magnetic shielding system of a glass absorbing cell with Cs alkali metal vapors includes a pair of rectangular magnetic shields arranged in such a way that the inner magnetic shield surrounds the cell, and the outer magnetic shield surrounds the inner magnetic shield, the outer shield being airtight, and the inner shield having through holes, the axis of which coincides with the direction of propagation of laser radiation, is perpendicular to the larger plane of the rectangular screen, and the process of the cell is oriented in the direction of the long edge of the screen rectangle. The hole in the inner magnetic screen on the side of the laser radiation is provided with a window. The internal magnetic screen is provided with means for heating and thermal stabilization of the absorbing cell. Bias coils are also installed inside the inner screen.

EFFECT: reducing the size of the device and its power consumption.
