The remarkable phenomena in ultrafast light-matter interactions manifested as an evolution of one-dimensional metal nanoparticles in liquid ablation are observed. The polycrystalline copper nanowires with a length of 1.0 µm and a diameter of 85 nm are successfully formed only under the linear-polarized laser irradiation. The growth mechanism of copper nanowires under the femtosecond laser irradiation was suggested to be a nucleation growth process. The formation mechanism of copper nanowires can be interpreted in terms of a created pattern via coupling between photon and surface plasmon waves; consequently a material could memorize the direction of the light polarization.
