The application discloses a wide-spectrum multi-wavelength laser frequency stabilization system of an atomic transition reference, and a wide-spectrum multi-wavelength laser frequency stabilization method of an atomic transition reference, wherein the spectrum peak of an atomic hyperfine structure obtained by saturated absorption spectrum is used to realize the frequency stabilization of laser, and the frequency multiplication and frequency mixing of laser are used to realize the calibration of the long-term stability of the wavelength meter to multiple laser wavelengths without affecting the wavelength accuracy of the calibration laser. In addition, the calibrated wavelength meter is used to accurately measure multiple laser wavelengths, and the hierarchical feedback adjustment mechanism of coarse adjustment and fine adjustment is used to realize the accurate locking of multiple laser wavelengths. The application overcomes the wavelength measurement drift of the wavelength meter caused by environmental changes, improves the measurement accuracy of the wavelength meter, guarantees the long-term stable and accurate operation of the wavelength meter, and guarantees the high-precision frequency stabilization of multiple laser wavelengths.
