摘要:

本文报道了利用非简并四波混频过程计算两个光学涡旋的拓扑荷的实验。结果表明,输出信号光携带的轨道角动量等于探测光和后向泵浦光的轨道角动量之差。Rb原子作为非线性介质,传递光的轨道角动量。

英文摘要:

In this paper, we report an experiment, which demonstrates computation of topological charges of two optical vortices via non-degenerate four-wave-mixing process. We show that the output signal beam carries orbital angular momentum which equals to the subtraction of the orbital angular momenta of the probe light and the backward pump light. The ⁸⁵Rb atoms are used as the nonlinear medium, which transfer the orbital angular momenta of lights.
