The paper examines a key part of the laser system used in cold atomic gravimeters. The optical system of an atomic gravimeter requires the stabilization of laser frequency offset from the atomic transition. In this connection, the authors propose an offset frequency stabilization method for a frequency-doubled fiber laser. The developed method is based on modulation transfer spectroscopy and the use of a broadband electro-optic modulator. An experimental setup for implementing the proposed method is described. In the study, error signals were obtained, enabling the offset frequency stabilization of a frequency-doubled fiber laser. In order to achieve the maximum amplitude of the error signal, the following parameters of the experimental setup were optimized: cell temperature, the intensity of the probe and saturation beams, as well as the amplitudes of signals fed to the electro-optic modulators. In addition, the effect of radiation polarization on the signal amplitude was examined. Circular polarization is shown to produce an error signal having a higher amplitude. The obtained results can be used in the development of a quantum gravimeter, quantum frequency standards, as well as in experiments involving laser cooling of atoms.
