AB  - We studied surface modification of a double layer protective coating on steel induced by single fs laser pulse irradiation in ambient air. The outer alumina (Al2O3) layer, which protects against aggressive environments, was 1.7 mu m thick and the titanium aluminum nitride (TiAlN) layer in contact with the steel surface had a thickness of 1.9 mu m. The pulses (lambda=775 nm, tau=200 fs) were generated by a Ti:sapphire laser source. The pulse energy was varied from 0.32 mu J to 50 mu J, corresponding to an incident laser fluence of 0.11 J cm(-2) to 16.47 J cm(-2). The surface damage threshold was found to be 0.20 J cm(-2) and the alumina layer removal was initiated at 0.56 J cm(-2). This selective ablation of alumina was possible in a wide range of fluences, up to the maximum applied, without ablating the TiAlN layer beneath. (C) 2012 Elsevier B.V. All rights reserved.
