The discussion centers on whether the Acousto-Optic effect varies with different colors of light, particularly in relation to wavelength. Participants note that most research focuses on light as a whole rather than individual wavelengths, suggesting a potential wavelength dependence due to factors like dispersion and the strain-optic tensor. It is acknowledged that significant energy is required to observe measurable effects, and the material's dispersive nature can influence the outcome. References to academic texts such as "Fundamentals of Photonics" and "Acousto-Optics" are provided for further reading. Overall, the conversation emphasizes the complexity of the Acousto-Optic effect and its relationship with different wavelengths.
