The application of ultra-short waveform-controlled laser fields to nanostructured materials enables the generation of localized near-fields with well-defined spatiotemporal field evolution. The optical fields that can be tailored on sub-wavelength spatial and attosecond temporal scales have a high potential for the control of ultrafast processes at the nanoscale, with important implications for laser-driven electron acceleration, extreme ultraviolet (XUV) light generation, and nanoscale electronics operating at optical frequencies.
