摘要：

We report the results of the development and production of a quantum frequency standard (QPS) based on the coherent population trapping (CPT) resonance observed on the D-1 absorption line of Rb-87 atoms. The effect of various physical factors on the QFS frequency is studied, and the optimal physical parameters of the device to attain the best frequency stability are determined. The measured relative frequency instability (Allan deviation) is similar to 9 x 10(-12) for the averaging time of 1 s, 3 x 10(-13) for 1000 s, and 1.5 x 10(-12) for 24 hours. For a volume of 60 cm(3), the power consumption of the entire device is 300 mW. The designed QFS can be used in a new-generation satellite navigation systems with increased accuracy and reliability, as well as for solving a number of other problems of science and technology.
