Periodic surface structures induced by femtosecond laser single pulse and pulse trains on metals

Abstract: We experimentally investigate the formation of nanostructures on the surfaces of aluminum and copper with femtosecond laser single pulse and pulse trains. Subwavelength ripples were obtained on the surface of aluminum. The ripples' period gradually increases as the laser pulse fluence increases. With a single pulse ablation of copper, interlaced ripple structures formed on the wall of the crater when the laser pulse number is 2000, the reason for interlaced ripple formation is also discussed. A large scale of … Show more
