Development of automatic control of optical signal gain in a atomic frequency standard based on rubidium-87 atoms

The necessity of developing a new design for automatic control of the optical signal gain to ensure the stability of the output parameters of the atomic frequency standard (AFS) based on rubidium-87 atoms under various external conditions of its operation is substantiated. This is especially true during the operation of this AFS as part of mobile objects for various purposes. A new scheme for automatic gain control in the optical path of an AFS based on rubidium-87 atoms is presented. The amplifier of the error signal formed on the photodetector for controlling the microwave signal is considered in detail. An experiment was carried out, and its final metrological characteristics were presented for the atomic frequency standard based on rubidium atoms - 87 with automatic gain control. The validity of the developed automatic amplification scheme for the new frequency standard based on rubidium atoms-87 is confirmed.
