根据国产商品激光管的拍频调谐特性,我们设计并实现了用锁相技术稳定横向塞曼激光,获得的频率稳定性达2×10~(-11)(1S),同一支激光管使用半年,光频的最大相对频偏不超过5×10~(-9)。本文还就观察到的拍频波形崎变现象进行了讨论。
According to the beat frequency tuning characteristics of the domestic laser tube, we designed and implemented the stable lateral Zeeman laser with the phase-locked technique to obtain the frequency stability of 2 × 10 ~ (-11) (1S). The same laser tube was used for six months , The maximum relative frequency deviation of optical frequency does not exceed 5 × 10 ~ (-9). This article also discusses the observed beating waveforms.
