Laser Treatment of Titanium in Hexane at Various Pressures and the Formation of Periodic Structures

Abstract

Laser-induced periodic surface structures are a universal phenomenon that can be observed on almost any material after irradiation with linearly polarized laser beams, especially when using femtosecond laser radiation. Over the past few years, research activity in the field of surface-periodic structures has significantly increased, since their generation in a one-step process provides an easy way to nanostructure and functionalize the surface to control optical, mechanical or chemical properties. The paper presents the results of a femtosecond laser treatment of titanium in a hexane medium at various pressures. The morphology of the treated surfaces was studied under various modes of laser exposure, using optical and scanning electron microscopy.
