Description
  • Postup na poli standartů optických frekvenčních hřebenů je orientován femtosekundovým hřebenům stabilizovaným optickou frekvenční syntézou. Takový laser generuje množství koherentních frekvenčních složek světla v určité oblasti vlnových délek. Hodnota opakovací frekvence femtosekundových pulsů určuje frekvenční vzdálenost těchto komponent. Pokud je tento laser kontrolován, např. pomocí atomových hodin, máme zajištěno velmi stabilní komponenty. Současná definici délkové jednotky je založena na znalosti rychlosti světla. Nabízíme netradičním způsobem přímý přenost frekvenční stability komponent módově vázaného laseru na síť diskrétních a stabilních délek reprezentovaných vzdáleností mezi dvěma zrcadly optického rezonátoru.

  • The progress in the field of optical frequency standards is oriented to femtosecond mode-lock lasers stabilized by technique of the optical frequency comb. Such a laser produces a supercontinuum light, which is composed of a cluster of coherent frequency components in certain interval of wavelengths. A value of the repetition rate of femtosecond pulses determines (in the frequency domain) spacing of these coherent components. If we control the mode-lock laser by means of i.e. atomic clocks we ensure frequency of these components very stable. With respect to definition of SI unit one meter on basis of speed of light the stabilized mode-lock laser can be used for implementation of this definition very non-traditional way. In the work we present our proposal of a system, which converts excellent frequency stability of components generated by the mode-lock laser to a net of discrete absolute lengths represented by a distance of two mirrors of an optical resonator.
