Photo-induced thermal radiation within multilayers optics

Abstract

Exact models of photo-induced temperature and thermal radiation are presented for optical coatings submitted to spatiotemporal regimes. Results are useful to analyze and predict thermal processes in optical thin films at different temporal and spatial scales. They also open a door to control the emissivity patterns of multilayers.

Development of an experimental facility for the measurement of photo-induced thermal emission in interferential filters

“…Most of these contributions show measurements of temperature elevation, with the aim of determining thermal parameters such as effusivity of conductivity. A 4D exact model for temperature and photo-induced thermal radiation has been developed at Fresnel Institute [21], [22], [23]. In the continuity of this work, we here present an experimental setup that leads to measurements of photoinduced thermal emission, in nanosecond regime, for broadband absorbers and metallic monolayers.…”

Molecular Dynamics Simulation of Laser Induced Heating of Silicon Dioxide Thin Films

“…Initially, the models describing LID were based on continual approaches including heat equations, kinetic equation, Boltzman equation, and so on [1,[7][8][9]. In recent decades, due to significant progress in high-performance computing, it has become possible to apply the methods of atomistic simulation for studying the laser radiation interaction with condensed matter [10][11][12].…”
