Book Synopsis Femtosecond Laser-Matter Interaction by : Eugene G. Gamaly
Download or read book Femtosecond Laser-Matter Interaction written by Eugene G. Gamaly and published by CRC Press. This book was released on 2011-10-06 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first comprehensive treatment of the interaction of femtosecond laser pulses with solids at nonrelativistic intensity. It connects phenomena from the subtle atomic motion on the nanoscale to the generation of extreme pressure and temperature in the interaction zone confined inside a solid. The femtosecond laser-matter interaction has already found numerous applications in industry, medicine, and materials science. However, there is no consensus on the interpretation of related phenomena. With mathematics kept to a minimum, this is a highly engaging and readable treatment for students and researchers in science and engineering. The book avoids complex mathematical formulae, and hence the content is accessible to nontechnical readers. Useful summaries after each chapter provide compressed information for quick estimates of major parameters in planned or performed experiments. The book connects the basic physics of femtosecond laser-solid interactions to a broad range of applications. Throught the text, basic assumptions are derived from the first principles, and new results and ideas are presented. From such analyses, a qualitative and predictive framework for the field emerges, the impact of which on applications is also discussed.

Available in PDF, EPUB and Kindle. Book excerpt: This book describes the ultra-short laser–matter interactions from the subtle atomic motion to the generation of extreme pressures inside the bulk of a transparent crystal. It is the successor to Femtosecond Laser–Matter Interactions: Theory, Experiment and Applications (2011). Explanation and experimental verification of the exceptional technique for the phase transformations under high pressure are in the core of the book. The novel phase formation occurs along the unique solid-plasmasolid transformation path: the memory of the initial state is lost after conversion to plasma. New phase forms from chaos during the cooling to the ambient. The pressure-affected material remains detained inside a pristine crystal at the laboratory tabletop. Unique super-dense aluminium and new phases of silicon were created by the confined micro-explosions. The text also describes the recent studies that used the quasi-non-diffracting Bessel beams. The applications comprise the new high-pressure material formation and micromachining. The book is an appealing source for readers interested in the cutting-edge research exploring extreme conditions and creating nanostructures at the laboratory tabletop.

Book Synopsis Laser-Matter Interaction for Radiation and Energy by : Hitendra K. Malik
Download or read book Laser-Matter Interaction for Radiation and Energy written by Hitendra K. Malik and published by CRC Press. This book was released on 2021-03-14 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: The interaction of high-power lasers with matter can generate Terahertz radiations that efficiently contribute to THz Time-Domain Spectroscopy and also would replace X-rays in medical and security applications. When a short intense laser pulse ionizes a gas, it may produce new frequencies even in VUV to XUV domain. The duration of XUV pulses can be confined down to the isolated attosecond pulse levels, required to study the electronic re-arrangement and ultrafast processes. Another important aspect of laser-matter interaction is the laser thermonuclear fusion control where accelerated particles also find an efficient use. This book provides comprehensive coverage of the most essential topics, including Electromagnetic waves and lasers THz radiation using semiconducting materials / nanostructures / gases / plasmas Surface plasmon resonance THz radiation detection Particle acceleration technologies X-ray lasers High harmonics and attosecond lasers Laser based techniques of thermonuclear fusion Controlled fusion devices including NIF and ITER The book comprises of 11 chapters and every chapter starts with a lucid introduction to the main topic. Then sub-topics are sedulously discussed keeping in mind their basics, methodology, state-of-the-art and future perspective that will prove to be salutary for readers. High quality solved examples are appended to the chapters for their deep understanding and relevant applications. In view of the nature of the topics and their level of discussion, this book is expected to have pre-eminent potential for researchers along with postgraduate and undergraduate students all over the world.
Book Synopsis Femtosecond Physics by : Stefano Spezia
Download or read book Femtosecond Physics written by Stefano Spezia and published by Arcler Press. This book was released on 2018-12 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Femtosecond physics is a novel branch of the theoretical physics, which investigates the interaction of atoms and molecules with pulsed or continuous wave lasers. In particular, this book treats the laser-matter coupling in a non-perturbative way using both approximate and numerical solutions of the Time-Dependent Schrödinger Equation (TDSE). Here, with the exception of one case study, the electromagnetic field is classically treated. Several physical phenomena ranging from ionization of atoms and molecules to their dissociation and the control of photochemical reactions are presented and discussed. This book begins with a wide Section 1, which deals with the TDSE and in particular, with its solutions. Initially, it considers only those cases exactly soluble, such as a class of potentials for which the TDSE with position-dependent mass allows reduction to a stationary Schrödinger equation, a time-dependent anharmonic oscillator, and at last, the derivation of a general form of the imaginary effective potential that relates the TDSE to the generalized Schrödinger equation with a memory kernel. Section 2 focuses on the field-matter interaction in quantum two-level systems, and in particular, a derivation of analytic broadband /2 and pulses that perform exact, or asymptotically exact, excitation of spin systems, presenting a nontrivial dynamic connection between nonlinear spin and linear spring systems. Finally, the last Section 3 considers several cases of atoms and molecules in strong laser fields. In detail, this section discusses a kinematic mechanism underlying the recently discovered 'near-zero energy structure' in the photoionization of atoms in strong mid-infrared laser fields and presents a number of benchmark calculations for intense short-pulse laser interactions with small atoms and molecules. Moreover, Section 3 presents a theoretical approach to investigate the high-order harmonic generation in the nano-graphene molecules and describes the few-electron ultrastrong light-matter coupling in a quantum LC circuit.

Book Synopsis Materials Interaction with Femtosecond Lasers by : Bernd Bauerhenne
Download or read book Materials Interaction with Femtosecond Lasers written by Bernd Bauerhenne and published by Springer Nature. This book was released on 2021-10-25 with total page 554 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a unified view of the response of materials as a result of femtosecond laser excitation, introducing a general theory that captures both ultrashort-time non-thermal and long-time thermal phenomena. It includes a novel method for performing ultra-large-scale molecular dynamics simulations extending into experimental and technological spatial dimensions with ab-initio precision. For this, it introduces a new class of interatomic potentials, constructed from ab-initio data with the help of a self-learning algorithm, and verified by direct comparison with experiments in two different materials — the semiconductor silicon and the semimetal antimony. In addition to a detailed description of the new concepts introduced, as well as giving a timely review of ultrafast phenomena, the book provides a rigorous introduction to the field of laser–matter interaction and ab-initio description of solids, delivering a complete and self-contained examination of the topic from the very first principles. It explains, step by step from the basic physical principles, the underlying concepts in quantum mechanics, solid-state physics, thermodynamics, statistical mechanics, and electrodynamics, introducing all necessary mathematical theorems as well as their proofs. A collection of appendices provide the reader with an appropriate review of many fundamental mathematical concepts, as well as important analytical and numerical parameters used in the simulations.

Download or read book Theoretical Femtosecond Physics written by Frank Großmann and published by Springer Science & Business Media. This book was released on 2013-07-16 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: Theoretical investigations of atoms and molecules interacting with pulsed or continuous wave lasers up to atomic field strengths on the order of 10^16 W/cm2 are leading to an understanding of many challenging experimental discoveries. This book deals with the basics of femtosecond physics and goes up to the latest applications of new phenomena. The book presents an introduction to laser physics with mode-locking and pulsed laser operation. The solution of the time-dependent Schrödinger equation is discussed both analytically and numerically. The basis for the non-perturbative treatment of laser-matter interaction in the book is the numerical solution of the time-dependent Schrödinger equation. The light field is treated classically, and different possible gauges are discussed. Physical phenomena, ranging from Rabi-oscillations in two-level systems to the ionization of atoms, the generation of high harmonics, the ionization and dissociation of molecules as well as the control of chemical reactions are presented and discussed on a fundamental level. In this way the theoretical background for state of the art experiments with strong and short laser pulses is given. The text is augmented by more than thirty exercises, whose worked-out solutions are given in the last chapter. Some detailed calculations are performed in the appendices. Furthermore, each chapter ends with references to more specialized literature.

Download or read book Femtosecond-Scale Optics written by Dong Chin Sun and published by . This book was released on 2016-04-01 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: A femtosecond laser is a laser which emits optical pulses with a duration well below 1 ps (¬ ultrashort pulses), i.e., in the domain of femtoseconds. It thus also belongs to the category of ultrafast lasers or ultrashort pulse lasers. The generation of such short pulses is nearly always achieved with the technique of passive mode locking. The growth of the femtosecond duration range is certainly one of the most brilliant achievements of laser physics. With progress in ultrashort ultraintense laser technologies the peak power of a laser pulse increases year by year. These new instruments accessible to a large community of researchers revolutionized experiments in nonlinear optics because when laser pulse intensity exceeds or even approaches intra-atomic field strength the new physical picture of light-matter interaction appears. Laser radiation is efficiently transformed into fluxes of charged or neutral particles and the very wide band of electromagnetic emission (from THz up to x-rays) is observed. Ultrashort laser pulses, with durations approaching the timescales of fundamental atomic and molecular processes, are useful in a range of scientific disciplines. They deliver energy so quickly that new processes and observations are possible. Their short duration allows them to probe delicate living structures without destroying them and make material modifications on the micron scale with minimal or precisely controllable heat effects. This field of researches is in rapid progress now.Femtosecond-Scale Optics provides depicts of current developments and original results in some specific areas of this very wide scientific field. This text will be of interest for those specialized in the subject of laser-matter interactions.
Book Synopsis Femtosecond Laser Filamentation by : See Leang Chin
Download or read book Femtosecond Laser Filamentation written by See Leang Chin and published by Springer Science & Business Media. This book was released on 2010-03-10 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book attempts to give a discussion of the physics and current and potential applications of the self-focusing of an intense femtosecond laser pulse in a tra- parent medium. Although self-focusing is an old subject of nonlinear optics, the consequence of self-focusing of intense femtosecond laser pulses is totally new and unexpected. Thus, new phenomena are observed, such as long range lam- tation, intensity clamping, white light laser pulse, self-spatial ltering, self-group phase locking, self-pulse compression, clean nonlinear uorescence, and so on. Long range propagation at high intensity, which is seemingly against the law of diffraction, is probably one of the most exciting consequences of this new sub- eld of nonlinear optics. Because the intensity inside the lament core is high, new ways of doing nonlinear optics inside the lament become possible. We call this lamentation nonlinear optics. We shall describe the generation of pulses at other wavelengths in the visible and ultraviolet (UV) starting from the near infrared pump pulse at 800 nm through four-wave-mixing and third harmonic generation, all in gases. Remotely sensing uorescence from the fragments of chemical and biological agents in all forms, gaseous, aerosol or solid, inside the laments in air is demonstrated in the labo- tory. The results will be shown in the last part of the book. Through analyzing the uorescence of gas molecules inside the lament, an unexpected physical process pertaining to the interaction of synchrotron radiation with molecules is observed.
