摘要/Abstract

摘要： 超稳激光是将激光频率稳定在超稳定光学腔的谐振频率上产生的，为了研制可搬运光钟所需的超稳钟激光，需要研制可搬运超稳定光学腔。通过光学腔的有限元分析，设计了一个振动敏感度低且结构稳健性好的可搬运光学腔，其腔长为30 cm，是目前已知腔长最长的可搬运光学腔。光学腔沿三个正交方向的振动敏感度分别为：沿光学腔腔轴方向（水平），1.4 × 10-10 g-1；垂直光学腔腔轴方向（水平），1.5 × 10-10 g-1；垂直光学腔腔轴方向（竖直），1.2 × 10-10 g-1。腔的振动敏感度略优于普通水平放置的光学腔,且腔具有更高的结构稳健性，可水平或者竖直安装。该光学腔设计可用于研制可搬运光钟。

Abstract: Ultra-stable lasers are generated by stabilizing their frequencies to the resonances of ultra-stable optical cavities. In ordertodevelopultra-stable clocks laser fortransportable optical clocks, transportable ultra-stable optical cavities are needed to be developed. Afterthe finite element analysis,the vibration-insensitive and structure-robust transportable optical cavitywas designed, whose length is 30 cm and is currently the longest among transportable optical cavities to our best knowledge. The vibration sensitivities of the cavity in three orthogonal directions were measured to be, along the cavity axis (horizontal), 1.4 × 10-10 g-1; cross the cavity (horizontal), 1.5× 10-10 g-1; cross the cavity (vertical), 1.2× 10-10 g-1. The cavity has slightly better vibration sensitivity compared with normal horizontal-placed optical cavities, and is more robustthuscan be mounted horizontally or vertically. The cavity can be used to develop atransportable optical clock.
