Abstract

The effect of laser treatment on copper irradiated by a Nd:YAG laser was investigated by optical microscopy, scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) and Auger electron spectroscopy (AES). Wettability measurements were taken previously on the laser treated samples and the results showed interesting changes. In this paper the surfaces of the copper samples were analyzed with optical microscopy, SEM, XPS and AES in four laser power parameter. The SEM observations demonstrate that in this laser beam power range the level of surface modification is not affected by the laser power. According to the XPS and AES results we can say that the measurements do not show exact connections between the oxidation state and the wettability of the laser treated surface.
