摘要:

我们报告的非破坏性成像的光学捕获的氟化钙(CaF)分子使用原位$Λ$增强灰色糖蜜冷却。与破坏性共振成像相比,获得了$200$倍的荧光,并且捕获的分子保持在$20\,μ\text{K}$的温度下。所获得的散射光子的数量使得能够以高保真度对单个分子进行非破坏性单次检测。

英文摘要:

We report non-destructive imaging of optically trapped calcium monofluoride (CaF) molecules using in-situ $Λ$-enhanced gray molasses cooling. $200$ times more fluorescence is obtained compared to destructive on-resonance imaging, and the trapped molecules remain at a temperature of $20\,μ\text{K}$. The achieved number of scattered photons makes possible non-destructive single-shot detection of single molecules with high fidelity.
