“…This facilitates the access to ultrashort, extreme-ultraviolet light pulses at laboratory scales [33,34,35] and makes HHG valuable for novel experimental realizations such as attosecond spectroscopy [22,23] or nanoscale photonic imaging [21].…”

“…Recent years have shown significant progress in translating concepts from attosecond and strong-field science [22] into the areas of ultrafast nano-optics and plasmonics. 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].…”

“…High-order harmonic up-conversion of intense laser radiation in gaseous media was first discovered in the late 1980s [18,19,20] and allows for new experimental strategies in nanoscale photonic-imaging [21] or ultrafast spectroscopy [22,23] by providing fully coherent attosecond light pulses at extreme-ultraviolet (EUV) wavelengths. State-of-the-art HHG concepts typically utilize moderately focused, ultrashort laser pulses from kHz amplifier systems to reach intensities in excess of 10 13 W/cm 2 (for infrared light frequencies), which are necessary to drive the HHG process in an atomic gas.…”

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

“…Due to their broad bandwidths, ultrashort attopulses [1][2][3][4][5] excite molecules to coherent non equilibrium electronic wavepackets on a time scale shorter than the response of the nuclei. As a result, the non equilibrium electron density is a coherent superposition of several electronic states and can beat between different parts of the molecule.…”

Dynamical computations demonstrate considerable selectivity over the fragmentation channels of the LiH molecule via the polarization and the carrier envelope phase (CEP) of a single ultrashort one cycle strong IR pulse. For aligned molecules, control of the CEP allows building non stationary coherent electronic wave packets of contrasting ionic character, either Li δ + H δ − or Li δ − H δ + . The complementary coherences are maintained all the way to dissociation. The direction of the electric field at its maximum points either towards the Li or towards the H atom, which selectively steers the nuclear dynamics to specific dissociation products.3

“…Extension to the attosecond realm called for new paradigms [13] on how we conceive and control the interaction of light with matter. In principle, and from a pure time domain perspective, a light field embodies enormously higher resolution than that typically exploited in femtosecond experiments.…”

Abstract-Tracing the dynamics of electrons inside atoms molecules or solids as they occur in real time resides at the forefront of modern science and technology. Advances in attosecond physics over the last decade and beyond are now enabling this essential experimental capability. Here we discuss some of the key developments in light sciences that made possible attosecond metrology and control of electronic processes inside matter on native time scales. These developments hold the promise for new, fundamental insights into the innerworkings of the microcosm as well as the identification of innovative routes for light-based electronic and photonic devices operating at PHz rates.
