我们通过组合相对于强泵浦光束频率偏移的弱探测光束，研究旋转介质对轨道角动量 (OAM) 承载光束的影响。我们展示了旋转多普勒效应如何通过介质的外部旋转来改变光与物质的相互作用。这种相互作用导致吸收随着介质的机械旋转速度而增加，并且吸收率取决于光束的 OAM。
We investigate the effect of a rotating medium on orbital angular momentum (OAM)-carrying beams by combining a weak probe beam shifted in frequency relative to a strong pump beam. We show how the rotational Doppler effect modifies the light-matter interaction through the external rotation of the medium. This interaction leads to an absorption that increases with the mechanical rotation velocity of the medium and with a rate that depends on the OAM of the light beam.
