Surface temperature-laser radiation

[Behrouz]

Hello,
I'm looking for the governing equations for the laser radiation on a surface. I understand there are several types and methods. I was wondering if there is an equation to show all the parameters in calculating a surface temperature after laser radiation for a specific time. Some of the parameters I can imagine are the thermophysical properties of the irradiated body and then the laser characteristics (e.g. frequency, energy).
Any advice would be appreciated.

In general, necessary parameters of irradiated substrate are:
Thermal conductivity, thermal capacity, reflectivity and emissivity.
Because thermal conductivity and emissivity parameters have strong dependence on temperature, analytical solutions are unknown. You can search on CNC machining forums for laser irradiation response of specific materials - laser cutters are recently quite popular in DIY.
