“…The feasibility of nanostructure-enhanced HHG has been proved already by several theoretical studies conducted independently [46,65,66,67]. However, no experimental demonstration has yet been reported except for our HHG data [24,58] from bow-ties.…”

“…Long plasmonic field decay might have caused the linewidth narrowing [66], which is however not proved yet. No attention was paid to the second or higher-order diffraction signals because they were buried below the noise floor in our measurement; the grating efficiency for the second order diffraction was one order of magnitude less than that for the first order.…”

“…[13,14] Another key example of this development was the report of high-harmonic generation (HHG) in plasmonic bow-tie antennas [24], that is, the integration of the most prominent strong-field effect of gaseous media [20,33] into a nanostructure. Despite triggering widespread theoretical [46,65,66,67] and experimental [26,28] efforts, subsequently, this effect has remained rather elusive. Important issues in this respect are whether plasmonic nanostructures can generally sustain sufficient intensities for HHG (refs [29,68]), if other fundamental limitations to the process exist [28], and what the ultimate prospects of ultrafast extreme-ultraviolet (EUV) nano-optics are.…”

“…Numerous characteristic nonlinear optical phenomena, such as above-threshold and strongfield photoemission, have become accessible using local field enhancements in metal nano-tips [12,62,13,14,15], resonant optical antennas [24,28,16,81], nanoparticles [17], rough surfaces [63], and plasmonic waveguides [26,15]. These experimental studies are paralleled by increasing theoretical efforts of describing strong-field effects at surfaces and in optical near fields [82,83,64], with a particular emphasis on nanostructure-enhanced high-order harmonic generation (HHG) [46,65,66,84,67,85,86,87,88,89,90]. Currently, some debate exists about experimental reports of nanostructure-enhanced HHG [24,26,15], following the demonstration of the predominance of incoherent extreme-ultraviolet (EUV) fluorescence caused by multiphoton and strong-field atomic excitation and ionization [28,81].…”

The present (cumulative) thesis examines fundamentals of nanostructure-enhanced extreme-ultraviolet light generation in noble gases using two different nanostructure geometries for local field-enhancement. Specifically, resonant antennas and tapered hollow waveguide nanostructures are utilized to enhance low-energy femtosecond laser pulses, which in turn induce light emission from excited xenon, argon and neon atoms and ions. Spectral analysis of this radiation reveals that coherent high-order harmonic generation is not feasible under the examined conditions, contrary to former expectations and reports. Instead, the spectral characteristics unequivocally identify that incoherent fluorescence from multiphoton excited and strong-field ionized gas atoms is the predominant process in such schemes. Furthermore, novel nanostructure-enhanced effects are reported such as surface-enhanced fifth-order harmonic generation (from bow-tie nanoantennas) and the formation of a bistable nanoplasma (in a hollow waveguide). These effects offer intriguing links between nonlinear nano-optics, plasma dynamics and extreme-ultraviolet radiation.v vi

“…051401 Recent advances in nanoscience and nanotechnologies are creating new avenues for designing and making nanometerscale metal structures which respond to irradiation with electromagnetic radiation by creating a tunable induced electric field near the metal surface [1,2]. This induced "plasmonic" field originates in the incident-field-driven coherent collective motion of conduction electrons which, when stimulated near its natural resonance (plasmon) frequency, generate a very large induced polarization in subwavelength-size structures on substrate surfaces [3][4][5][6][7][8][9] and isolated nanoparticles [10]. Near metallic nanospheres and for linearly polarized incident radiation [10][11][12][13][14][15][16], the oscillating induced polarization gives rise to oscillating plasmonic fields with dipole-like angular distribution oriented along the polarization direction of the incident radiation [17].…”

Streaked photoemission from nanostructures is characterized by size-and material-dependent nanometer-scale variations of the induced nanoplasmonic response to the electronic field of the streaking pulse and thus holds promise of allowing photoelectron imaging with both subfemtosecond temporal and nanometer spatial resolution. In order to scrutinize the driven collective electronic dynamics in 10-200-nm-diameter gold nanospheres, we calculated the plasmonic field induced by streaking pulses in the infrared and visible spectral range and developed a quantum-mechanical model for streaked photoemission by extreme ultraviolet pulses. Our simulated photoelectron spectra reveal a significant amplitude enhancement and phase shift of the photoelectron streaking trace relative to calculations that exclude the induced plasmonic field. Both are most pronounced for streaking pulses tuned to the plasmon frequency and retrace the plasmonic electromagnetic field enhancement and phase shift near the nanosphere surface.

The detailed understanding of plasmonic excitations in solids requires imaging techniques that resolve their spatiotemporal evolution [3,16]. While ultrafast laser technology is available in many laboratories worldwide, allowing the resolution of various aspects of the electronic dynamics during the infrared (IR)-pulse-streaked extreme ultraviolet (XUV) photoionization of gaseous atoms with a precision of about 10 as [21], a promising emerging line of attosecond science targets the electronic dynamics in solids, biomolecules, and nanostructures [2,22]. These highly time-resolved investigations on solid targets address effects that are absent in isolated atoms in the gas phase, such as the propagation of photoexcite...
