The extraordinarily precise technology allows a direct link from RF standards to the optical light sources in the near infrared regime. The optical frequency comb technique is used in laser-based precision Spectroscopy , which uses interference effects to generate a series of femtosecond-length pulses. Lasers which use the frequency comb technique allow for precise readings from light of all colors. The optical frequency synthesizer technology is based on a Femtosecond laser frequency comb. It requires the stabilization of two important parameters: Repetition rate ωr and offset frequency ω0. From the exact knowledge of these two radio frequencies one can derive the optical frequency of any mode ωn=n ωr + ω0 This technique has also been extended to the extreme ultraviolet range, which may allow for more precise clocks and X-ray frequencies. Theodor W. Hänsch and John L. Hall share the Nobel Prize in Physics 2005 for contributions to the development of laser-based precision spectroscopy, including the optical frequency comb technique. Some applications for the extraordinary precise technology frequency comb technique are frequency chain generation, optical atomic clocks, ultra high precision spectroscopy, and GPS technology.
