论文摘要
量子气体显微镜的出现使得在空间分辨率水平的原位探测超低气态。然而，对于基于线性光学的所有技术，对较小的长度尺度以及三维系统的探测的研究从根本上受到了限制。在这里，我们报告了高分辨率离子显微镜作为研究量子气体的多功能且强大的实验工具。该仪器显然可以在光学晶格中解析原子，其间距为532美元，\ text {nm} $在50个站点的视野上，并在至少$ 70 \，μ\ text {m} $的顺序上提供了极大的景深。使用一个简单的模型，我们从数据中提取了可实现的大约200美元\，\ text {nm} $的上限。我们展示了一种脉冲操作模式，将来将实现3D成像，并允许研究离子杂质和Rydberg物理学。
The advent of the quantum gas microscope allowed for the in situ probing of ultracold gaseous matter on an unprecedented level of spatial resolution. The study of phenomena on ever smaller length scales as well as the probing of three-dimensional systems is, however, fundamentally limited by the wavelength of the imaging light, for all techniques based on linear optics. Here we report on a high-resolution ion microscope as a versatile and powerful experimental tool to investigate quantum gases. The instrument clearly resolves atoms in an optical lattice with a spacing of $532\,\text{nm}$ over a field of view of 50 sites and offers an extremely large depth of field on the order of at least $70\,μ\text{m}$. With a simple model, we extract an upper limit for the achievable resolution of approximately $200\,\text{nm}$ from our data. We demonstrate a pulsed operation mode which in the future will enable 3D imaging and allow for the study of ionic impurities and Rydberg physics.
