• several tens of microns on the surface of a gold taper [11]. These results have been confirmed by three-dimensional finite difference time domain (FDTD) simulations [11]. These theoretical investigations and experimental demonstrations suggest that pump–probe studies employing adiabatic nanofocusing are

The finite-difference time-domain (FDTD) included a section of the substrate, enclosed in all directions by perfectly matched layers (PML) to avoid spurious reflections. The central area of 5×5
