Light in a medium: do phonons store light energy?

AI Thread Summary
Phonons in a transparent medium can absorb and re-emit light, potentially moving to a higher energy state during this process. This mechanism differs from electron interactions due to phonons having a continuous range of energy states. The absorption and re-emission of light by phonons introduces delays between interactions, which disrupts coherent transmission. Consequently, this results in significant scattering due to the varying phases of re-emitted waves. The discussion highlights the complexities of light behavior in mediums and the implications for coherent light transmission.

When light travels through a transparent medium and is absorbed then re-emitted, do the phonons just move to a higher energy state after absorption? Is it the same as absorption and re-emission of light by electrons, aside from having a continuous range of available energies?

absorption and re-emission of light by electrons,
That process would introduce an unknown delay between absorption and emission with each photon interaction. That would not sustain a coherent transmission through the medium. Drastic scattering would result from the spread in phases of each re-emitted wave.
 
Thread 'A quartet of epi-illumination methods'
Well, it took almost 20 years (!!!), but I finally obtained a set of epi-phase microscope objectives (Zeiss). The principles of epi-phase contrast is nearly identical to transillumination phase contrast, but the phase ring is a 1/8 wave retarder rather than a 1/4 wave retarder (because with epi-illumination, the light passes through the ring twice). This method was popular only for a very short period of time before epi-DIC (differential interference contrast) became widely available. So...
I am currently undertaking a research internship where I am modelling the heating of silicon wafers with a 515 nm femtosecond laser. In order to increase the absorption of the laser into the oxide layer on top of the wafer it was suggested we use gold nanoparticles. I was tasked with modelling the optical properties of a 5nm gold nanoparticle, in particular the absorption cross section, using COMSOL Multiphysics. My model seems to be getting correct values for the absorption coefficient and...
