随着电子学技术的蓬勃发展,微波频率综合技术已成为一种通用技术,人们只要将微波频率综合器的输入端接上一个高精度的原子钟(如铯原子钟)就可以得到0～40 GHz范围内的任意频率输出,其极限精度可达微赫兹量级。但是在光学频率波段(10~(14)Hz),要实现光学频率综合(即将一个高精度的光学基准频率任意精密地传递到另一个光学频率)是世界级的难题。随着光学频率梳及其频率锁定技术的发明,光学频率综合原则有了解决的方案,但是由
With the rapid development of electronics technology, microwave frequency synthesis technology has become a universal technology. People only need to connect the input of microwave frequency synthesizer to a high-precision atomic clock (such as cesium atomic clock) to get the range of 0-40 GHz Within any frequency output, the ultimate accuracy of up to the order of microseconds. But in the optical frequency band (10 ~ (14) Hz), it is a world-class challenge to achieve optical frequency synthesis (ie, to pass precisely one high-precision optical reference frequency to another optical frequency as accurately as possible). With the invention of the optical frequency comb and its frequency locking technique, there is a solution to the principle of optical frequency synthesis,
