A frequency comb is a spectrum that comprises a series of discrete, equally spaced elements. The most popular mechanism used to generate a frequency comb is stabilization of the pulse train by a mode-locked laser. In 2005, John L. Hall and Theodor W. Hänsch shared one half of the Nobel Prize in Physics for their contributions to this important area. Recently developed techniques based on femtosecond frequency combs can be utilized in a wide range of advanced measurement applications, including high-precision spectroscopy, atomic clocks, chemical sensors, super lasers, long-distance communications, and LIDAR.
