We investigate the laser damage resistance and optoelectronic properties of thin metallic and semiconducting films used in high power beam steering metasurfaces. We find that gold exhibits the best laser damage resistance, and large absorption losses arising from high carrier concentrations and low mobilities in alternative plasmonic thin films lead to exacerbated degradation and poorer laser damage performance. We will also present results of laser-induced dewetting on thin metallic films deposited on substrates with different optical environments (such as plasmonic films and cavities). We observe that the morphology of dewetting is sensitive to the nonlocal optical environment. This work was performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344. LLNL-ABS-845919. DE-NA0004007.
