	abstract = {Optical nanoantennas concentrate light into their local fields. The field concentration property is governed by the plasmonic resonances and their interference. Here, we present a method for controllable local-field interferences in the hot spot of nanorods and experimentally demonstrate that the field enhancement can be tuned in a wide range. For this, we design nanoparticles with given phase relations between their plasmonic eigenmodes and at the same time tune the phase between the components of the external field by changing its polarization state to achieve in-phase excitation of the plasmon modes. Strong-field photoemission is applied to probe the field enhancement property of the nanorods employing femtosecond pulses of different polarization states. Our findings provide a new degree of freedom in plasmonic resonance tuning and may inspire diverse designs of local-field responses and expand the applications in nanoscale sensing, spectroscopy, and dynamically tunable devices.},

	abstract = {Ultrafast optoelectronics promises a several-order-of-magnitude speed-up of computational devices. In recent years several experiments emerged that demonstrated the possibility of steering electrons in matter with optical fields on femtosecond timescales and this way they established building blocks for PHz devices [1,2]. Such a typical experiment usually exploits the carrier-envelope phase (CEP) of laser pulses which causes symmetry breaking driving an oriented current in a medium. These ultrafast, CEP-dependent currents appear in a wide range of media spanning graphene, semiconductors or dielectrics. A common feature of these experiments is that currents are detected using metal electrodes and slow electrical circuit is contacted to the illuminated volume. This raises the question on what basis the current transfer from the medium to the electrodes is and whether the optical-to-electrical conversion is possible without the loss of bandwidth. A recent study [3] hints that the photocurrent transfer might be non-local, i.e. there is no need for physical transport of carriers from the volume to the electrodes. Having that in mind, we experimentally studied the relationship between the ultrafast photocurrent current, material, laser beam and geometry. We observed signatures that can be modelled with the Ramo-Shockley theorem that support the manifestation of non-local, i.e. quasi-instantaneous dynamics.},

Thus, the measurement and control of CEP is essential for applications of few-cycle lasers. Currently, there is no robust method for measuring the non-trivial spatial CEP distribution of few-cycle laser pulses. Here, we demonstrate a compact on-chip, ambient-air, CEP scanning probe with 0.1 µm 3 resolution based on optical driving of CEP-sensitive ultrafast currents in a metal−dielectric heterostructure. We successfully apply the probe to obtain a 3D map of spatial changes of CEP in the vicinity of an oscillator beam focus with pulses as weak as 1 nJ. We also demonstrate CEP control in the focal volume with a spatial light modulator so that arbitrary spatial CEP sculpting could be realized.},

	abstract = {Irradiation of solids with ultrashort pulses using laser sources in the mid-infrared (mid-IR) spectral region is a yet predominantly unexplored field that opens broad possibilities for efficient and precise surface texturing for a wide range of applications. In the present work, we investigate both experimentally and theoretically the impact of laser sources on the generation of surface modification related effects and on the subsequent surface patterning of metallic and semiconducting materials. Through a parametric study we correlate the mid-IR pulsed laser parameters with the onset of material damage and the formation of a variety of periodic surface structures at a laser wavelength of λL = 3200 nm and a pulse duration of τp = 45 fs. Results for nickel and silicon indicate that the produced topographies comprise both high and low spatial frequency induced periodic structures, similar to those observed at lower wavelengths, while groove formation is absent. The investigation of the damage thresholds suggests the incorporation of nonlinear effects generated from three-photon-assisted excitation (for silicon) and the consideration of the role of the non-thermal excited electron population (for nickel) at very short pulse durations. The results demonstrate the potential of surface structuring with mid-IR pulses, which can constitute a systematic novel engineering approach with strong fields at long-wavelength spectral regions that can be used for advanced industrial laser applications. © 2022 Elsevier B.V.},
