摘要
In this research, we examine laser-induced periodic surface structures (LIPSS) [1] on conducting indium-tin-oxide thin films produced by 2-µm femtosecond pulses in ambient air. We present diverse surface morphologies around the focal spot and assign local threshold peak intensity values to the different structure formations.
