frequency comb

Such a frequency comb is similar to a ruler.

At the heart of the system is a laser that emits a broad frequency comb.

A professor was looking for a research assistant to study femtosecond optical frequency combs.

Dr. Hänsch first proposed the technique, called the optical frequency comb, in the late 1970's.

A frequency comb allows a direct link from radio frequency standards to optical frequencies.

To measure an unknown frequency, the frequency comb output is dispersed into a spectrum.

A purely electronic device, which generates a series of pulses, also generates a frequency comb.

Currently, optical frequency combs have provided a much simpler method of measuring optical frequencies.

In this manner, locking of the frequency comb output to an atomic standard can be performed in a single step.

The frequency comb now serves as the basis for optical frequency measurements in large numbers of laboratories worldwide.

A frequency comb is a light source whose spectrum consists of a series of discrete, equally spaced elements.

The breakthrough which led to a practical frequency comb was the development of technology for stabilizing the carrier-envelope offset frequency.

Due to the high precision of the theory also very high precision for the experiments is needed, which utilize a frequency comb.

This series of sharp spectral lines is called a frequency comb or a frequency Dirac comb.

This problem has been solved with the development of self-referenced mode-locked lasers, commonly referred to as femtosecond frequency combs.

If the frequency comb is evenly spaced then, conveniently, the Fourier transform of the output waveform is the image itself.

New technologies, such as femtosecond frequency combs, optical lattices and quantum information, have enabled prototypes of next generation atomic clocks.

He developed an optical "frequency comb synthesiser", which makes it possible, for the first time, to measure with extreme precision the number of light oscillations per second.

See, for example, Optical frequency comb for dimensional metrology, atomic and molecular spectroscopy, and precise time keeping.

They have been produced in microscopic glass spheres or toruses, for example, with applications in lasing, optomechanical cooling, frequency comb generation and sensing.

The researchers at the Max Planck Institute of Quantum Optics thus speculated about new methods, and developed the optical frequency comb synthesizer.

Hall shared half of the Nobel prize with Theodor W. Hänsch for their pioneering work on laser-based precision spectroscopy, and the optical frequency comb technique.

Applications for the frequency comb technique include optical metrology, frequency chain generation, optical atomic clocks, high precision spectroscopy, and more precise GPS technology.

Prize: Michael Mei and Ronald Holzwarth, Menlo Systems GmbH, "Optical frequency comb technique"

During the late 1990s, he and his coworkers developed a new method to measure the frequency of laser light to an even higher precision, using a device called the optical frequency comb generator.
