High speed laser induced periodic structure generation using femtosecond laser on surface of titanium

Abstract

Abstract In this work femtosecond laser wavelength of 800nm, 1KHZ repetition rate and pulse length 100fs irradiation surface texturing has been used. The laser surface texturing is distinguished itself than other conventional processing due to its simplicity controllability and reproducible in creating various structures and wide range of applications. A labview compact zaber xy stage is used for this purpose and investgated the high scanning speed (20mm/s,10mm/s) surface structures on Titanium plate. The velocity of sample position used as function to generate modified surface structures. The surface textured studied by effect of variation of scanning velocity and this texturing process has been done in air medium by above selected parameters. FESEM sample characterization study of surface morphology has been done to details study of textured sample surface.
