Abstract The formation of laser-induced deformation patterns on thin films and surfaces may be described by a dynamical model for the coupled evolution of defect densities and deformation fields of the material. Increasing laser intensity induces deformational instability, which may be characterized in the framework of linear stability analysis of undeformed states. However, the selection and stability of deformation patterns are determined by nonlinear effects, and require full nonlinear analysis in the post-bifurcation regime. Analytical and numerical results are presented for uniform laser irradiation of pure metallic thin films, and the conditions for pattern selection are discussed.
