Abstract
Based on the demand for the stability of the Mach–Zehnder optical interferometer, we proposed and designed a system that can achieve fast and precise locking at any phase point in one period. The locking system is simple and is easy to operate. The core elements are an electro-optic modulator (EOM), which can generate different phase shift on the vertically polarized light and horizontally polarized light, and a PID feedback. The experimental results show that for the MZ interferometer, the system can achieve fast, accurate and long-term locking at any phase point. The accuracy of the phase lock can be controlled within 1.05°or 0.0029λ with the intensity of the interference beams of 0.335 mW. This locking technology can be applied in the field of precision measurement in the future.
