Abstract

We explore laser-induced dewetting of thin gold films deposited on different underlayers consisting of optical cavities of gold and silica. Our observations indicate that the morphology and optical response of laser-exposed regions are sensitive to the optical environment in vicinity of the dewetting layer.
