Fourteen years after the first proposal of a fractal theoretical model to understand the dynamics of laser produced plasma, a complete image of the model is projected on a wide range of empirical data related to laser produced plasmas.The book tackles the two sides of laser produced plasmas with experimental data on a wide range of materials, from metallic alloys to geological samples and the associated mathematical model is developed in the multifractal theory of motion. A new perspective is explored in analyzing and interpreting the data collected by electrical or optical methods, focusing especially on the charged particles dynamics and the nature of fractal fluctuations and their influence during measurements as well as to the scattering process and plasma splitting phenomena, all seen through the lens of multifractal physics.The book offers the best presentation of the multifractal theoretical model for the study of transient phenomena in laser produced plasmas, which focus leads to a balanced development of the model showcasing both the flexibility and the unique vision of a multifractal mathematical apparatus.

Ultrashort laser pulse systems allow examination of intense, ultrafast laser-plasma interactions. More specifically, intense laser irradiation can induce short xuv/x-ray bursts from the surface of condensed phase targets. Ultrafast xuv/x-ray detection is needed to understand laser-plasma interactions in this dynamic regime. Support of the Stockpile Stewardship and Management Program requires this critical understanding. Our effort here has been to extend understanding of atomic-scale dynamics in such environments with the goal of developing next generation ultrafast xuv/x-ray diagnostics where the sensors will be the atoms and ions themselves and the time resolution will approach that of the induced atomic transitions ((almost equal to) a few femtoseconds). Pivotal contributions to the rapidly developing field of highly nonperturbative interactions of ultrashort pulse lasers with atoms/ions have been made at this laboratory. In the visible/infrared wavelength regions the temporal and spectral content of ultrashort laser pulses are now reliably monitored within a single pulse using frequency resolved optical gating (FROG) which is based on rapid nonlinear optical processes such as the Kerr effect. New applications of this basic concept are still being developed. Corresponding detection for the xuv/x-ray wavelengths does not exist and is urgently needed in many laboratory programs. The FROG technique cannot be applied in the xuv/x-ray region. Current x-ray streak camera technology is limited to (almost equal to)0.5 picosecond resolution.

This book documents the recent vivid developments in the research field of ultrashort intense light pulses for probing and controlling ultrafast dynamics. The recent fascinating results in studying and controlling ultrafast dynamics in ever more complicated systems such as (bio-)molecules and structures of meso- to macroscopic sizes on ever shorter time-scales are presented. The book is written by some of the most eminent experimental and theoretical experts in the field. It covers the new groundbreaking research directions that were opened by the availability of new light sources such as fully controlled intense laser fields with durations down to a single oscillation cycle, short-wavelength laser-driven attosecond pulses and intense X-ray pulses from the upcoming free electron lasers. These light sources allowed the investigation of dynamics in atoms, molecules, clusters, on surfaces and very recently also in nanostructures and solids in new regimes of parameters which, in turn, led to the identification of completely new dynamics and methods for controlling it. Example topics covered by this book include the study of ultrafast processes in large molecules using attosecond pulses, control of ultrafast electron dynamics in solids with shaped femtosecond laser pulses, light-driven ultrafast plasmonic processes on surfaces and in nanostructures as well as research on atomic and molecular systems under intense X-ray radiation. This book is equally helpful for people who would like to step into this field (e.g. young researchers), for whom it provides a broad introduction, as well as for already experienced researchers who may enjoy the exhaustive discussion that covers the research on essentially all currently studied objects and with all available ultrafast pulse sources.

Diese Arbeit leistet einen Beitrag zum Verständnis der ultraschnellen Abtrags- und Schmelzphänomene von Festkörpern bei Anregung mit Laserstrahlung großer Intensität. Fundamentale Aspekte des laserinduzierten Abtrags von Reinmetallen (Au, Al, Cu, Fe, W) mit Ultrakurzpuls-Laserstrahlung wie z.B. Laser-Materie-Wechselwirkung, Plasmabildung, Verdampfung und Schmelzdynamik wurden untersucht. Darüber hinaus wurde Schmelzen und Schweißen von technischem Borosilikatglas mittels hochrepetierender Ultrakurzpuls-Laserstrahlung untersucht. Für Untersuchungen der transienten laserinduzierten Vorgänge auf unterschiedlichen Zeitskalen wurden neuartige experimentelle Verfahren entwickelt und eingesetzt. Pumpprobe Photographie wurde für zeitaufgelöste Messungen auf einem erweiterten zeitlichen Detektionsbereich bis ca. 2 Mikrosekunden mit Sub-Pikosekunden Auflösung realisiert. Für Detektion von transienten Brechungsindexmodifikationen und Morphologieänderungen wurde ein neuartiges, zeitaufgelöstes Verfahren zur quantitativen Phasenmikroskopie (TQPm) entwickelt. Die geometrischen und zeitlichen Profile der eingesetzten Laserstrahlung großer Intensität wurden beim Abtragen von Metallen untersucht. Aufheizung des Materials bedingt durch spontane verstärkte Emission mit Pulsdauer im Nanosekundenbereich führt zu einem materialabhängigen Temperaturanstieg von mehreren hundert Kelvin und wurde numerisch untersucht. Zeitaufgelöste Schattenphotographie und quantitative Messungen des Abtragsvolumens von Metallen wurden in unterschiedlichen Umgebungen durchgeführt. Im untersuchten zeitlichen Detektionsbereich kann die beobachtete Abtragsdynamik in mindestens vier charakteristischen Zeitregimes klassifiziert werden: Ausbreitung von dichtem Materialdampf und Plasma, Verdampfung aufgrund der Nukleationseffekte, Abtrag in Form von flüssigen Schmelzstrahlen und Erstarrung. Basierend auf experimentellen Ergebnissen wurde ein qualitatives Modell für laserinduzierten Abtrag von Metallen bei großen Strahlungsintensitäten aufgestellt, welches bedeutende Unterschiede zum Abtragen bei schwellennahen Intensitäten aufweist. Insbesondere sind physikalische Vorgänge die im Zusammenhang mit Materieüberhitzung stehen wie z.B. Phasenexplosion und “boiling crisis”, als entscheidende Abtragsphänomene suggeriert worden. Laserinduziertes Schmelzen von technischem Borosilikatglas mit hochrepetierender Ultrakurzpuls-Laserstrahlung wurde mittels TQPm zeitaufgelöst untersucht. Experimentelle Ergebnisse weisen transiente Brechungsindexmodifikationen auf welche auf Ionisationsprozesse und Verdichtung der Materie zurückzuführen sind. Als eine wichtige Anwendung dieser Prozesse wurde das Mikroschweißen von dünnen Glas- und Silizium-Platten demonstriert. Beim Schmelzen von Material an Substrat-Grenzflächen können konsistente Schweißnähte im Mikrometerbereich erzeugt werden.

This book describes the application of ultrafast laser science and technology in materials and processing relevant to industry today, including ultrafast laser ablation where fundamental studies have led to the development of the world's first femtosecond photomask repair tool. Semiconductor manufacturing companies worldwide use the tool to repair photomask defects, saving hundreds of millions in production costs. The most up-to-date ultrafast laser technologies are described and methods to generate high harmonics for photoelectron spectroscopy of industrially important materials are covered, with an emphasis on practical laboratory implementation. Basic device physics merged with photoemission studies from single- and polycrystalline materials are described. Extensions to new methods for extracting key device properties of metal-oxide-semiconductor structures, including band offsets, effective work functions, semiconductor band bending and defect-related charging in a number of technologically important gate oxides are detailed. Polycrystalline photovoltaic materials and heterostructures as well as organic light emitting materials are covered. This book describes both the history, and most recent applications of ultrafast laser science to industrially relevant materials, processes and devices.
