In this work we propose a simple one-step method for creation of hybrid Au/Si micro- and nanostructures with strong nonlinear response. We demonstrate that such structures depending on laser structuring parameters can produce strong enhancement of second harmonic signal compared to the initial Au/Si films or/and broadband white-light photoluminescence in the visible optical range. To explain this dependence, the studies of the fabricated structures were carried out by the Raman spectroscopy demonstrating strong correlation between phase composition of the structures and their nonlinear properties. We believe that proposed structures can be used as efficient nonlinear souses for different applications in bioimaging and nanospectroscopy.
