The temperature in the laser irradiation area of an amorphous iron-based ribbon was calculated. As a result of the calculation a spatial temperature distribution and its time dependence were structured which allowed reproducing the geometric and structural characteristics of exposed areas. Simultaneously, an irradiated amorphous alloy was investigated by scanning electron microscopy which allowed determining the geometric and structural characteristics of these areas experimentally and obtaining their dependencies on the laser pulse parameters. The results of theoretical calculations were compared with the experimental data.
