Abstract

A method of analytical and numerical calculation of the absorption coefficient of laser radiation was proposed and tested based on the results of a simplified experimental cutting setup. The results are compared with available theoretical predictions and experimental data the literature forecasts in a wide range of angles of inclination. A significant difference between the absorption coefficients for mild steel used in the theory and reconstructed from experimental data. The obtained absorption coefficient can be used for further modeling of laser material processing technologies.
