通过用辐射压力“推动”激光冷却的 9Be+ 离子旋转云，在库仑晶体中产生局部激发的等离子体波。这些波形成静止尾流，通过离子荧光对多普勒频移的依赖性直接成像，并且板几何结构中的理论计算被证明可以准确地再现这些图像。该技术展示了一种激发和研究冷离子云中波的新方法。
Locally excited plasma waves are generated in a Coulomb crystal by "pushing" with radiation pressure on a rotating cloud of laser-cooled 9Be+ ions. The waves form a stationary wake that is directly imaged through the dependence of the ion fluorescence on Doppler shifts, and theoretical calculations in a slab geometry are shown to accurately reproduce these images. The technique demonstrates a new method of exciting and studying waves in cold ion clouds.
