Methods of calculating heating effects in various cases of interest have been found in the literature. The results on metallic absorbing surfaces are easily adapted to other surfaces. The use of classical thermodynamics formalism is generally made. In metals, light is absorbed by interaction with electrons. A quantum of optical energy is absorbed by an electron which is raised to a higher energy state in the conduction band. The excited electrons collide with lattice photons and with other electrons and give up their energy. These are the same collision processes that govern the transfer of heat. The concept of temperature will be valid, and we are justified in applying the usual equations for heat flow. Starting from the well-known temperature distribution due to an instantaneous point source in an unbounded medium, we formulate a solution in a moving slab for the axially symmetric heat source. I have also shown Brugger’s result for a particular case of the above result
