Abstract

Oxide nano-particles have some important applications, so the possibility to generate oxide nano-particles was provided on some solid material via femtosecond laser in atmosphere. Experimental results present that nanoparticles' size distribution and average size can be directly controlled by laser fluences and pulse numbers. Femtosecond laser ablation can be an efficient process to produce oxide nano-particles around the irradiated area on some solid materials in atmosphere..
