摘要:
Atomic clocks based on optical frequency transitions are supposed to have great potential to get extreme accuracy.Many optical clocks have shown better accuracy than the best microwave atomic fountain clocks based on cesium.[1-3] Strontium is a good candidate for building optical clocks because of its convenient level structure for laser cooling and ultra narrow clock transition.
