Femtosecond Laser Surface Processing (FLSP) is a technology to fabricate micro/nano surface structures. These patterned surface structures show great importance in many applications, especially in controlling the wettability of the surface. Imprinting is a typical method for manufacturing large volumes of surfaces. This study combines two processes (FLSP and stamping) together to produce a surface structure similar to the original FLSP surface. In the first step, micro/nano structured surface mounds were fabricated by femtosecond laser processing. Then, these FLSP surfaces served as molds for subsequent imprinting to replicated the “negative” surface on a blank material. Surface morphology and peak-to-valley roughness …
