摘要：

The optical system plays a significant role to cesium atomic fountain clocks, which manipulates and detects population of cesium atoms. This paper presents a compact optical system for cesium atomic fountain clocks. The optical system provides two beams with 32mW separately for cooling atoms and six beams of 12mW respectively for trapping atoms with the frequency tuning from 80MHz to 220MHz. The relative intensity noise of the detect laser beam reduces from 1.33x10(-6) Hz to 1.52x10(-10) Hz at 1Hz by the laser power stabilization system. The optical system operates continuously for 30 days with the fluctuation of optical power less than 3% approximately. And the frequency stability is 3x10(-15) at 1000s. The results show the optical system satisfies with the needs of our cesium atomic fountain clock developed and establishes the foundation for cesium atomic fountain continuous operation.
