Laser micro-texturing has emerged in the last decade as an effective tool for biomaterials surface engineering which resulted in significant improvement in cell/surface interactions. This paper intends to mainly investigate nanosecond fiber laser micro-texturing on biocompatible materials, e.g., pure titanium. The effect of process parameters, including laser frequency, power, interaction time and spot size, on the induction of the micro-self-assembled structures are investigated. Scanning Electron Microscope (SEM) and Profilometry analyses are carried out to demonstrate the size, shape, and roughness of the generated micro-structures. X-Ray Diffraction (XRD), Energy dispersive spectrophotometric (EDS), and hardness testing are also performed to investigate mechanical, physical and chemical properties of such structures. Analysis of the experimental results suggests that the self-generated micro-structures are highly influenced by the process parameters in particular the laser frequency and interaction time.
