Abstract
The coupling between surface deformation and defect dynamics may be at the origin of deformation patterns in thin films under laser irradiat ion. We analyze a simple model describing the dynamics of such systems in the case of focused laser irradiation. We show, through linear, no nlinear, and numerical analysis, how rose deformation patterns, with t he petal number increasing with laser intensity, naturally arise in th is model, in agreement with experimental observations.
