Волоконний ербієвий синтезатор частоти навігаційних супутникових систем

Abstract

The physical foundations for the creation of a compact fiber femtosecond frequency synthesizer designed to transfer the stability of the frequency of the optical standard (Nd: YAG / I2) to the radio range and, thus, to implement on its basis the MFOG. A new method of stabilizing the spectrum components of a femtosecond fiber Erbium laser by means of simultaneous phase auto-fixing of optical frequencies of the extreme spectral components of an extended-to-octave spectrum of femtosecond radiation by frequency of Nd: YAG / I2 optical standard is proposed. The method allows to ensure complete stabilization of the generated comb of optical frequencies without the use of the nonlinear interferometer traditionally used for these purposes and, thus, increase the stability of the system to external perturbations.
