The fabrication of titanium (Ti) porous structures covered with periodic nanostructures from micro Ti powders by femtosecond laser-induced sintering and simultaneous laser-induced periodic surface structures (LIPSS) are demonstrated. Different types of structures are obtained only by controlling the laser power of a femtosecond laser at wavelength 800 nm: sintered structures and sintered/melted structures with periodic nanostructures of period 550 similar to 650 nm.
