Abstract

The invention relates to a pumping light frequency stabilization method for an SERF atomic spinning gyro. A pumping light frequency stabilization device is used for achieving pumping light frequency stabilization device, the pumping light frequency stabilization device comprises a pumping light frequency stabilization atomic air chamber, a heating device, a detector, a feedback signal processor and a laser controller, a beam of light is split from a light path, the split light passes through the air chamber only comprising alkali metal atoms, and high-stability frequency can be achieved by a narrow absorption peak; and meanwhile, by additionally arranging the feedback signal processor and the laser controller, frequency stabilization control is performed on output light frequency of pumping light, high-stability frequency is achieved, and a complicated light path brought by saturated absorption frequency stabilization is prevented.

Description

technical field [0001] The present invention relates to a pumping light frequency stabilization method for SERF atomic spin gyroscopes, in particular to a semiconductor laser frequency stabilization method mainly derived from alkali metal absorption peaks, belonging to the laser stabilization method for SERF atomic spin gyroscopes frequency technology field. Background technique [0002] The output wavelength of the semiconductor laser will change accordingly with the temperature and current of the laser, which will have a certain impact on the application of the laser. Especially in the SERF atomic spin gyroscope, the frequency stability of the pump laser directly determines the stability of the atomic polarizability, and ultimately affects the bias stability of the gyroscope. When using a gyroscope to achieve high-precision measurement, in order to ensure the output accuracy of the gyroscope, the output laser is required to have as high monochromaticity as possible.
