Herein, we report the scheme of an optically pumped atomic clock based on a cold cesium atomic beam source. We propose the laser system and physical mechanism of this atomic clock, wherein the atomic beam travels in an upper parabolic trajectory, the

Compared to other commercial atomic clocks in the time keeping field, the greatest advantage of cesium beam atomic clocks is their superior long-term stability. Compared to magnetic state-selection clocks, optically pumped cesium beam atomic clocks h

In this paper, we present a linewidth locking method to control the microwave power in optically pumped cesium-beam frequency standards. The responses of optically pumped cesium-beam tubes and classical cesium-beam tubes are analyzed and compared aga

This paper proposes a miniature optically pumped cesium-beam atomic frequency standard with a volume of 38.4 l and a weight of 28 kg and examines the main factors that affect its signal-to-noise ratio (SNR). Methods to improve the SNR are proposed, w

As optical frequency standard [1]–[4] and frequency comb developed with quite high precision(10−18 or 10−19) and commercial H-maser developed with quite good short-term stability(10−15), the only and core competitiveness of Cesium beam freque

Microwave power is an important factor on the long-term stability of the cesium beam (OPCB) frequency standard. In this paper, we present a new linewidth locking method to control the microwave power in OPCB frequency standards in theory. The respons
