我们展示了一个基于激光的飞秒可切换非弹性电子分束器。相干光相位调制的200 keV电子在一个薄的电子透明膜准备一个高纯度的三维动量叠加态，其特征在于在能量和动量空间。
We demonstrate a laser-based and femtosecond-switchable inelastic electron beam splitter. Coherent optical phase modulation of 200-keV electrons at a thin electron-transparent membrane prepares a high-purity three-dimensional momentum superposition state, characterized in energy and momentum space.
