论文摘要
我们报告了在整体环型腔中捕获和冷却Li-6原子。为了使腔对用于调节原子相互作用的磁场不敏感，我们完全由融合的二氧化硅和Zerodur构造。使用氢氧化物键组装组件，我们显示的可以与超高真空兼容。在高弹性环腔中进行反向散射会导致陷阱强度波动和加热，但是在相处的双向泵中，可以使陷阱寿命足够长，可以在交叉光束陷阱（单向泵）和2D Lattice Trap（BiDirectional pumperutional）中进行量子气体实验。
We report on trapping and cooling Li-6 atoms in a monolithic ring bowtie cavity. To make the cavity insensitive to magnetic fields used to tune atomic interactions, we constructed it entirely from fused silica and Zerodur. The components were assembled using hydroxide bonding, which we show can be compatible with ultra-high vacuum. Backscattering in high-finesse ring cavities readily causes trap intensity fluctuations and heating, but with phase-controlled bi-directional pumping the trap lifetime can be made long enough for quantum gas experiments in both the crossed-beam trap (unidirectional pump) and 2D lattice trap (bidirectional pump) configurations.
