Terahertz laser frequency combs
The development of optical frequency combs has had a revolutionary impact on high-precision metrology and spectroscopy, and the development was recognized with a Nobel Prize in 2005. At visible and near-infrared frequencies, the combs are often formed based on mode-locked lasers whose periodic pulse trains in the time domain naturally lead to frequency combs from the duality relation in Fourier...

متن کاملColloquium: Femtosecond optical frequency combs
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 spectrum produced by mode-locked lasers, which consists of a regular comb of sharp lines. Thus such a controlled mode-locked laser is a ‘‘femtosecond optical frequency comb generator.’’ For a sufficiently broad com...

متن کاملOptical Frequency Combs: From Frequency Metrology to Optical Phase Control
The merging of continuous wave laser-based precision optical-frequency metrology with mode-locked ultrafast lasers has led to precision control of the visible and near-infrared frequency spectrum produced by mode-locked lasers. Such a phase-controlled mode-locked laser forms the foundation of a “femtosecond optical-frequency comb generator” with a regular comb of sharp lines with well-defined f...
