We demonstrate machine-learning prediction of the 3D profiles of craters ablated by the intensity-modulated laser. After the supervised learning on the 3D profile data of the stainless steel ablated with the ramp intensity modulation, the prediction of the profiles for the validation set with 78 samples within an average error of 0.23 micrometers was achieved.
