Optical 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...
متن کاملTerahertz 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 کاملLossless equalization of frequency combs.
Frequency combs obtained by sinusoidal phase modulation of narrowband cw lasers are widely used in the field of optical communications. However, the resulting spectral envelope of the comb is not flat. We propose a general and efficient approach to achieve flat frequency combs with tunable bandwidth. The idea is based on a two-step process. First, efficient generation of a train with a temporal...
متن کاملX-ray frequency combs from optically controlled resonance fluorescence
An x-ray pulse-shaping scheme is put forward for imprinting an optical frequency comb onto the radiation emitted on a driven x-ray transition, thus producing an x-ray frequency comb. A fourlevel system is used to describe the level structure of N ions driven by narrow-bandwidth x rays, an optical auxiliary laser, and an optical frequency comb. By including many-particle enhancement of the emitt...
