Linear and Nonlinear Optical Properties of Cultural Heritage Materials — •Marta Castillejo — Instituto de Química Física Rocasolano, CSIC, Serrano 119, 28006 Madrid, Spain

The study of Cultural Heritage substrates and materials represents an interesting challenge due to their complex morphology, structure and composition. The identification of constituents, in often multilayer, multimaterial substrates, the study of the behaviour with ageing and of the response to irradiation by photon or particle beams, used for characterization or conservation purposes, are highly stimulating tasks, as multifaceted interactions among individual components induce important effects on the final encountered physical properties. This talk will focus on the linear and nonlinear optical properties of Cultural Heritage materials and components, on how these can be measured with unprecedented micrometric resolution and on how they provide information on the interactions among constituents. Changes experienced by these properties effected upon laser irradiation used for superficial cleaning or for analytical purposes will be also discussed. Examples on various types of substrates, including stone, paintings, metals and glasses will serve to illustrate the mentioned aspects.
