Reflexion and transmission in case of heating

[jk22]

Suppose a laser beam polarized arriving from vacuum to a medium. What are the reflexion and transmission powers taking into account heating. What equations could be used to solve this ?

It is unclear what are you asking here. Heating what?
You mean to ask how (or if) the reflection coefficients depend on temperature?

 

[jk22]

Yes, the beam heats the medium up and this will modify the reflected and transmitted intensities.

 

[nasu]

It may be just that the beam damages (changes) the quality of the surface and by this changes the amount of light reflected.
What is this medium?

From air to glass for example. I was wondering how to compute the absorbed power due to heating.
