- How to calculate the temperature change of a laser-irradiated material when the absorption, laser pulse energy, spot size, wavelength, pulse width, and frequency are known?
I am looking to approximately calculate the temperature change of a sample that was exposed to a laser pulse. Experimentally, we know the optical absorption, reflection, and transmission, as well as the source parameters for our laser system. I realize that I will have to make approximations about the thermal relaxation times, optical absorption mechanisms, and the fact that the absorbed energy is completely converted to thermal energy. I am simply trying to understand absolute thermal maximums from the sample from the laser exposure.
