Paper Abstract

In this paper, formation of microstructure on the surface of aluminum target is investigated. The target surface was irradiated by trains of nanosecond Nd:YAG laser in ambient air. The irradiation was performed at trains of 1 to 500 laser pulses with energies ranging from 0.1 to 0.4 mJ. Such laser pulse energies provided intensities at the order of 107 W/cm2at the target surface. Using optical microscope, the irradiated region of the target surface was characterized by measuring of microstructures depth and length. In this study the effects of laser pulse energy and the number of pulses in microstructure formation was inspected. The results show quasi-Gaussian profile for the distributions of microstructure depth and length.
