AI Technical Summary
In existing atomic clock systems, optical frequency shift is difficult to completely suppress, resulting in insufficient frequency stability and accuracy, as well as poor environmental adaptability, which affects its performance in high-precision applications.
A laser based on diffraction homogenization and closed-loop frequency stabilization control is used. The Gaussian beam is converted into a flat-top beam by the diffraction homogenizer, and high-precision frequency locking is achieved by combining modulation transfer spectroscopy technology, which dynamically corrects optical path distortion and improves system stability.
It significantly improves the frequency stability and accuracy of atomic clocks, enhances the system's environmental adaptability and robustness, reduces operational difficulty, and enables long-term stable operation in complex environments.
