AbstractEnergy coupling is a key phenomenon in material processing techniques that use lasers. It is a complex physical process which involves numerous parameters, such as a material's refractive index, laser wavelength, angle of incidence, polarization, temperature, power, power intensity, surface roughness, and surface coating. Although there are some empirical and theoretical models of the dependence of the energy coupling efficiency (also known as absorptivity) on individual and/or groups of parameters, to date, there is no comprehensive model that addresses the wide array of parameters that affect energy coupling for laser material interactions. To address this need, several of the available models are examined, and a generic methodology is introduced and used to de-couple, classify and regroup the parameters.
