摘要
En 中文
A compact modulation transfer spectroscopy (CMTS) module with high stability in frequency and robustness is realized for a transportable 87 Rb atomic gravimeter. The module is fabricated in a 91 mmx169 mmx60 mm box. The frequency instability achieved with CMTS is below 1.3 x 10(-13) /root tau in the short term, not exceeding 5 x 10(-12) until 1 x 10(5) s, which is the best performance of 87 Rb recorded so far in the literature. The achievement of high frequency stability with CMTS is discussed, analyzing the factors that impact frequency stability, with the Allan deviation measured under various conditions. This study offers a novel and efficient choice for applications employing the stabilized laser frequency and transportable system.
