我们展示了一个玻色爱因斯坦凝聚体的镱原子被困在一个一维（1D）的光学晶格使用超窄的光学transition 1 S 0 Participat 3 P2（m=−2）的光学磁共振成像（OMRI）。我们开发了一个真空室配备了薄玻璃细胞，它提供了高的光学访问，并允许磁线圈的紧凑设计。OMRI的测量光谱的线形很好地描述了在一维光学晶格中的原子的空间分布，与Escheras-Fermi近似和施加磁场梯度。所观察到的光谱表现出对应于光学晶格周期性的周期性结构。
We demonstrate optical magnetic resonance imaging (OMRI) of a Bose–Einstein condensate of ytterbium atoms trapped in a one-dimensional (1D) optical lattice using an ultra-narrow optical transition1S0↔3P2(m=−2). We developed a vacuum chamber equipped with a thin glass cell, which provides high optical access and allows a compact design of magnetic coils. A line shape of a measured spectrum of the OMRI is well described by a spatial distribution of the atoms in a 1D optical lattice with the Thomas–Fermi approximation and an applied magnetic field gradient. The observed spectrum exhibits a periodic structure corresponding to the optical lattice periodicity.
