摘要

在声光相互作用中，众所周知，光的频率和相位在透明介质和浑浊介质中都会发生超声波偏移，而且相位在浑浊介质中也会受到超声波调制。然而，人们一直不清楚在浊介质中，超声波引起的光频率和相位偏移与光相位调制之间是否存在内在联系。在这封信中，我们揭示了超声波引起的光学频率和相位偏移取决于浊介质声光相互作用中光学相位的调制。此外，频移光的强度与光学相位的调制有关。然后，随着光学相位调制幅度的增加，相位调制光包括相对较多的频率偏移较高的光波。最后，这些结论得到了外差实验的证实。

Dependence of the ultrasound-caused shifts in optical frequency and phase and the modulation of optical phase in acousto-optic interaction of turbid media

In acousto-optic interaction, it is widely known that the frequency and phase of light are ultrasound-shifted in both transparent and turbid media, and furthermore the phase is also ultrasound-modulated in turbid media. However, it has been unclear whether there is an inherent relationship between the ultrasound-caused shifts in optical frequency and phase and the modulation of optical phase in turbid media. In the letter, we reveal that the ultrasound-caused shifts in optical frequency and phase depend on the modulation of optical phase in acousto-optic interaction of turbid media. Additionally, the intensity of frequency-shifted light is related to the modulation of optical phase. Then, with the increase of the modulation amplitude of optical phase, the phase-modulated light comprises relatively more light waves with higher frequency shifts. At last, the conclusions are confirmed by heterodyne experiments.
