Colloquium: Femtosecond optical frequency combs

ST Cundiff, J Ye - Reviews of Modern Physics, 2003 - APS
Recently there has been a remarkable synergy between the technologies of precision laser
stabilization and mode-locked ultrafast lasers. This has resulted in control of the frequency …

Making optical atomic clocks more stable with 10−16-level laser stabilization

YY Jiang, AD Ludlow, ND Lemke, RW Fox… - Nature …, 2011 - nature.com
The superb precision of an atomic clock is derived from its stability. Atomic clocks based on
optical (rather than microwave) frequencies are attractive because of their potential for high …
