Abstract

TiO₂ thin films of different thicknesses were prepared by conventional electron beam deposition (EBD) and reactive low-voltage ion-plating (RLVIP) techniques. These samples were designed to investigate the thickness dependent optical and thermal properties of the TiO₂ coatings and the corresponding damage thresholds. In this paper we present a detailed comparison of the two groups of samples by using various photothermal techniques. The data reported include thermal conductivity, defect density, optical absorption, laser damage threshold, as well as laser conditioning effect by using Ar⁺ laser irradiation. The general trend shown by the data is that the ion-plated samples have higher absorption, lower damage threshold, yet better thermal conductivity, lower defect density, and almost perfect stability under Ar⁺ laser irradiation.
