Abstract

We study experimentally and theoretically the effects of intense laser beams interaction with metallic nanostructures in the ablation regime. Specifically, at high laser beam fluences we create ablation plasmas and study their spatio-temporal evolution as a function of the underlying metallic nanostructure. Our work hints the possibility of controlling ablation plasmas with properly selected systems structured at the nanoscale, offering new opportunities for a range of applications from compact accelerators and light sources to advanced manufacturing to plasma medicine.
