Dual-frequency laser frequency difference adjustment system and method based on stress transfer

Abstract

The application provides a dual-frequency laser frequency difference adjusting system and method based on stress transmission. The system comprises a dual-frequency laser and a detection component. The dual-frequency laser comprises a tube shell, a magnetic strip, a first mirror, a second mirror and a first deformation functional part. The first deformation functional part is connected between the first mirror and the tube shell. The first deformation functional part is configured to at least generate plastic deformation when subjected to external force, and transmit stress generated by the deformation of the first deformation functional part to the first mirror. The detection component comprises a polarizer, a detector and a processor. The detector is used to receive laser emitted from the dual-frequency laser and passing through the polarizer, and convert the laser into an electrical signal. The processor is used to receive the electrical signal and generate frequency difference information of two linearly polarized lights of the laser. According to the application, the damage to the dual-frequency laser can be reduced during the frequency difference adjusting process, the frequency difference stability of the dual-frequency laser can be improved, and the operation convenience of the frequency difference adjusting can be improved.
