States Introduction: Ultrashort pulsed (USP) laser offers athermal material ablation, which makes it a popular technology for conducting fine machining jobs. Nevertheless, due to lack of a mechanistic understanding of the laser/matter interaction, the laser machining practices are often trial-and-error, with no systematic method for generating proper machining recipes. In this work, we present a model for predicting the surface properties of a sample from the lasering/scanning parameters as

Development of such model is the first critical step towards constructing a recipe generator model that can prescribe the right set of lasering/scanning parameters for achieving the desired results. We established an interpolator that predicted two surface properties of depth of cut (DOC) and surface roughness (Sq) from lasering parameters and material type.
