| Abstract Scope |
Femtosecond laser surface processing (FLSP) offers a powerful method to functionalize surfaces by creating micro/nano-scale structures. However, quantifying the complex structures formed by FLSP poses a challenge. Graph theoretical (GT) approaches provide a solution by enabling accurate and quantitative analysis of FLSP images using topological parameters such as number of nodes, number of edges, average nodal degree, graph density, average path length, clustering coefficient etc. In this study, copper (Cu) samples were processed with varying pulse counts while keeping the peak fluence constant. Graph theory techniques were implemented using MATLAB and Python programming languages, and the topological parameters were tabulated and analyzed. Sub-surface analysis was conducted using focused gallium ion beam milling, and the analysis of these parameters provided valuable insights into the formation of onion-like layers. This research demonstrates the effectiveness of GT approaches in characterizing and differentiating FLSP structures, contributing to a better understanding of surface functionalization processes. |
