    Precise length etalon controlled by stabilized frequency comb

  • Original language description

    The progress in the field of optical frequency standards is oriented to femtosecond mode-locked lasers stabilized by technique of the optical frequency synthesis. Such a laser produces a number of coherent frequency components in certain interval of wavelengths. If we control the mode-locked laser by means of i.e. atomic clocks we ensure very stable frequency of these components. With respect to definition of SI unit one meter on the basis of speed of light, the stabilized mode-locked laser can be usedfor implementation of this definition in a non-traditional way. In the work we present our proposal of a system, which converts excellent frequency stability of components generated by the mode-locked laser to a net of discrete absolute lengths represented by a distance of two mirrors of an optical resonator.

    Přesný délkový etalon kontrolovaný stabilizovaným frekvenčním hřebenem

  • Czech description

    Optický frekvenční hřeben kontrolovaný, např. pomocí atomových hodin nabízí prostředek k definování přesné stabilní délky. Náš systém převádí velmi přesnou stabilitu jednotlivých komponent laseru generovanou módlokovaným laserem na síť diskrétních absolutních délek reprezentovaných vzdáleností zrcadel optického rezonátoru.
