我们展示了光的轨道角动量向冷铯原子系统转移的实验结果；利用非简并四波混频过程作为一种间接工具来观测这种转移。我们的实验尤其表明，光的轨道角动量能够通过冷原子样本中的光抽运，从一束光转移到以不同频率振荡的另一束光。
We present experimental results on the transfer of the orbital angular momentum of light to a system of cold cesium atoms; A nondegenerate four-wave mixing process was used as an indirect tool to observe this transfer. Our experiments show, in particular, that the orbital angular momentum of light can be transferred, via optical pumping in the cold atomic sample, from one beam to another oscillating at a different frequency.
