Formation of a system of microcraters on a titanium surface by femtosecond laser radiation under rapid cooling conditions
2013
Results of structuring a titanium surface with femtosecond laser radiation are reported. Formation of an ordered system of microcraters with a diameter of about 2 μm and a step of about 3 μm is observed. The character of this process is determined by the laser-beam transverse structure. The possibility of fixing the structures formed is provided by rapid cooling (using liquid nitrogen) of the laser-irradiated region. The potential of this treatment mode for nanostructuring surfaces of materials is considered.
