Deposition of Ablation Products from UV-Laser Irradiated Polymer Surfaces
Published online by Cambridge University Press: 15 February 2011
Abstract
The growth and structure of surface dendrites observed after UV-Iaser irradiation of polyethylene-terephthalate (PET) have been investigated. The lateral size and structure of dendrites is strongly influenced by the laser wavelength and ambient pressure. Pressure-dependent experiments demonstrate the importance of redeposition of ablation products onto the laser-modified surface. Different possible growth mechanisms are discussed.
