Thus, the electron pulse train stems from the interference of the "frequencycomb" of the above-threshold components. We discuss the use of such phase-locked continuum pulses in the realization of a new kind of ultrabroad frequencycomb for absolute frequency measurements throughout the visible spectrum. They have been produced in microscopic glass spheres or toruses, for example, with applications in lasing, optomechanical cooling, frequencycomb generation and sensing.

Nevertheless, the four-wave mixing effect above can create and stabilize a perfect frequencycomb in such a structure.

From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. In this manner, locking of the frequencycomb output to an atomic standard can be performed in a single step. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Such a frequencycomb is similar to a ruler.

He developed an optical frequencycomb synthesiser, which makes it possible, for the first time, to measure with extreme precision the number of light oscillations per second. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. With the refinement of the frequencycomb, these measurements have become much more accessible and numerous optical clock systems are now being developed around the world. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Existing frequency combs were too precise to be useful for astronomy, with teeth too close together. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Similar coherence lengths can be reached with optical frequency combs due to the narrow linewidth of each tooth. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. This problem has been solved with the development of self-referenced mode-locked lasers, commonly referred to as femtosecond frequency combs. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Currently, optical frequency combs have provided a much simpler method of measuring optical frequencies. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Frequency combs can be generated by a number of mechanisms, including amplitude modulation of a continuous wave laser or stabilization of the pulse train generated by a mode locked laser.
