Abstract

We present the fabrication of waveguides by laser ablation of metal targets on pyrex glasses. An horizontal position of the sample and the plate was found suitable to improve the effect of the plume in the sample with respect to the alternative vertical arrangement. We have analysed the longitudinal and transversal profiles, using a profilometer and have compared the results for the different configurations, speeds and metal targets. We show pictures of the surfaces, obtained by electron microscopy and confocal microscopy. We have studied the characteristics of the structures taking account the optical and thermal properties of the metal foils.
