This paper investigates the feasibility of generating micro-self-assembled structures on pure titanium using a nanosecond Ytterbium fiber laser. The effect of process parameters, including laser frequency, power, processing speed and spot size, on the induction of the micro-self-assembled structures is investigated. Scanning Electron Microscope (SEM) and Profilometry analyses are carried out to demonstrate the size, shape, and roughness of the generated micro-structures. Analysis of the experimental results suggests that the generation of self-assembled structures with a desired roughness is viable. It is also observed that the laser spot size can potentially control the local surface roughness when the other process parameters are fixed.
