Abstract

The production of clean energy is nowadays a very important and critical topic and Laser Fusion is one of the possibilities to achieve this goal. In order to improve the efficiency of this technology, one of the problematics is the increase in laser energy in the optical systems, and therefore the need for optical coatings able to sustain higher fluence. In this study, the contribution of the substrate surface quality on the optical performance and Laser Induced Damage Threshold (LIDT) will be investigated. Mirror coatings for a wavelength of 532nm will be coated using an Ion Beam Sputtering System on different types of glass substrates and the optical properties like scattering, absorption and Laser Damage will be presented and discussed.
