Is the Acousto-Optic Effect correlated to wavelength/colour?

AI Thread Summary
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.

Would the Acousto-Optic effect be different for different colours of light or rainbow? Or it would treat all wavelengths of light in a white beam the same? Would one colour witness a greater acousto-optic effect than the other? Please explain. Thank you.

what research have you done on this so far ?, considering this post is closely tied to your previous one
in which is was reasonably well established that significant energy was required to cause any measurable effect

This question is speaking purely of the Acousto optic effect in lasers and solids. Not liquids.

I see most research deals with the light as a whole and not the subsequent frequency components (separate colors) of light.

Would you mind linking to a few of your sources so we can look at them? I doubt many people are familiar with this topic and it would help if we were able to see some of this information for ourselves. Just looking at the wikipedia article, I'd think that dispersion would play a factor since the index of refraction changes with strain, but I know next to nothing about the topic or about how the devices are set up.

I mainly get text from research repositories related to university, that's why it may not be accessible if I link to papers in journals like I previously did. There are general papers available on google though. I will try to gather some links and post them. They are mainly around Crystals and Light/Sound Acoustic-Optic Effect, Seeing Sound with light and also, looking into carrying sound signal with light, using their interaction.

If the material is dispersive, there is definitely a wavelength-dependence on the effect, both from the strain-optic tensor and from the Bragg angle. Salen and Teich's "Fundamentals of Photonics" has a very readable chapter on acousto-optics, Korpel's "Acousto-Optics" is much more complete (and advanced).
 
I would like to use a pentaprism with some amount of magnification. The pentaprism will be used to reflect a real image at 90 degrees angle but I also want the reflected image to appear larger. The distance between the prism and the real image is about 70cm. The pentaprism has two reflecting sides (surfaces) with mirrored coating and two refracting sides. I understand that one of the four sides needs to be curved (spherical curvature) to achieve the magnification effect. But which of the...
