Ultrafast Near-Field Dynamics in Silver Nanowires Driven by Few-Cycle Short-Wave Infrared Pulses
Time-resolved imaging of plasmonic near fields is well-established at visible wavelengths but remains largely unexplored in the short-wavelength infrared (SWIR) range. Here, we use time-resolved photoemission electron microscopy (TR-PEEM) to directly visualize ultrafast plasmon dynamics in silver nanowires driven by a few-cycle SWIR pulses. We observe strong electric-field enhancement localized at
