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...

Optical Metrology Third Edition

The development of modern metrology and its role today.

Modern metrology is the result of more than 200 years of development that began with the creation of the decimal metric system at the time of the French Revolution and the beginning, at about the same time, of mass production using interchangeable parts. This article traces these developments and describes how world metrology is organized today and gives examples of applications of metrology sh...

Optical frequency comb metrology from infrared to extreme ultraviolet wavelengths

We report on frequency comb generation at 1.5 μm by injection of a CW laser in a hybridly1 mode-locked InAs/InP two-section quantum-dot laser (HMLQDL). The generated comb has > 60 modes spaced by ∼ 4.5 GHz and a -20 dBc width of> 100 GHz (23modes) at> 30 dB signal to background ratio. Comb generation was observed with the CW laser (red) detuned more than 20 nm outside the HMLQDL spectrum, spann...
