“…The formation of a gas plasma can be easily induced by electron discharges, which rely on direct or inductive ionization of a gas volume [57,55,115,97,98]. But intense laser radiation can also be utilized to obtain a plasma through multiphoton or strong-field ionization [30,116,117,118].…”

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

“…In some of these molecules, intense В-Х transitions may occur in the uv or vuv spectral ranges, providing for efficient conversion of the energy delivered to the discharge into optical radiation [9][10][11]. Barrier discharge (BD) excilamps are now widely used in photochemistry and microelectronics, for cleaning and modification of surfaces, for polymerization of lacquers and paints, in technologies of disinfection of industrial wastes, water, and air, and in biology and medicine [4,5].…”

533.915, 533.9.072, 533.932 The characteristics of xenon barrier-discharge excilamps have been calculated with the use of a onedimensional hydrodynamic model in the approximation of a nonlocal electric field. It has been shown that a two-peak mode of operation of the barrier discharge is realized in xenon excilamps. The 172-nm radiation of molecules prevails in the radiation of excilamps; the 147-nm resonance radiation makes no more than 1% of the overall radiation. The radiation intensity of xenon excilamps and their optical efficiency vary inversely on varying the parameters: the radiation intensity of a lamp falls, whereas its optical efficiency increases.

“…Over more than one and a half decade, starting from the works [1,2], there is an increasing interest in UV and VUV spontaneous radiation sources in which radiation of exciplex and excimer molecules is used [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Such sources were named as excilamps [10].…”

The paper is devoted to experimental study of discharge and radiation characteristics taking place in Xe one-barrier excilamps at broad variations of excitation pulse parameters and gas fill-pressures. The B-X band of the molecule Xe2 dominates the lamp spectrum and has high efficiency. Radiation of monatomic lines and luminescence of the lamp bulb can be observed too. The molecule Xe2* band B-X radiation of luminescence time dependence and luminescence of the lamp bulb quartz are similar, at the same time the radiation of Xe monatomic line = 467 nm has obviously some other form.Depending on excitation conditions, i.e. power, duration and excitation impulse form, a gas discharge Xe excilamp, different by homogeneity level and radiation efficiency types of discharge can be realized. Formation of discharge homogeneity is the necessary condition to obtain high efficiencies of excimer radiation in this type of lamp. In one-barrier xenon excilamps with internal small curvature of an electrode, a homogeneous discharge forms at pressures up to 300 Ton.
