The frequency stabilization of the diode laser. The absorption spectroscopy is used to stabilized the frequency of the diode laser. By optimizing of this facility, such as, the diode laser drive, frequency stabilization, absorption cell and optical component etc, high signal-to-noise ratio of differential error signal of absorption spectroscopy is achieved. Thus the sensitivity of frequency locking and long-term frequency stability are improved. In this item, an optical wavelength standard facility has been established. The repetition and stabilization of this standard facility can fulfill the calibration needs of the optical wavelength meter at present and in the future.
