Book Description
Self-focusing has been an area of active scientific investigation for nearly 50 years. This book presents a comprehensive treatment of this topic and reviews both theoretical and experimental investigations of self-focusing. This book should be of interest to scientists and engineers working with lasers and their applications. From a practical point of view, self-focusing effects impose a limit on the power that can be transmitted through a material medium. Self-focusing also can reduce the threshold for the occurrence of other nonlinear optical processes. Self-focusing often leads to damage in optical materials and is a limiting factor in the design of high-power laser systems. But it can be harnessed for the design of useful devices such as optical power limiters and switches. At a formal level, the equations for self-focusing are equivalent to those describing Bose-Einstein condensates and certain aspects of plasma physics and hydrodynamics. There is thus a unifying theme between nonlinear optics and these other disciplines. One of the goals of this book is to connect the extensive early literature on self-focusing, filament-ation, self-trapping, and collapse with more recent studies aimed at issues such as self-focusing of fs pulses, white light generation, and the generation of filaments in air with lengths of more than 10 km. It also describes some modern advances in self-focusing theory including the influence of beam nonparaxiality on self-focusing collapse. This book consists of 24 chapters. Among them are three reprinted key landmark articles published earlier. It also contains the first publication of the 1964 paper that describes the first laboratory observation of self-focusing phenomena with photographic evidence.

Book Description
This book is an interdisciplinary introduction to optical collapse of laser beams, which is modelled by singular (blow-up) solutions of the nonlinear Schrödinger equation. With great care and detail, it develops the subject including the mathematical and physical background and the history of the subject. It combines rigorous analysis, asymptotic analysis, informal arguments, numerical simulations, physical modelling, and physical experiments. It repeatedly emphasizes the relations between these approaches, and the intuition behind the results. The Nonlinear Schrödinger Equation will be useful to graduate students and researchers in applied mathematics who are interested in singular solutions of partial differential equations, nonlinear optics and nonlinear waves, and to graduate students and researchers in physics and engineering who are interested in nonlinear optics and Bose-Einstein condensates. It can be used for courses on partial differential equations, nonlinear waves, and nonlinear optics. Gadi Fibich is a Professor of Applied Mathematics at Tel Aviv University. “This book provides a clear presentation of the nonlinear Schrodinger equation and its applications from various perspectives (rigorous analysis, informal analysis, and physics). It will be extremely useful for students and researchers who enter this field.” Frank Merle, Université de Cergy-Pontoise and Institut des Hautes Études Scientifiques, France

Book Description
This book presents an overview of the state of the art of the developing topic of nonlinear optics with contributions from leading experts in the field in China, ranging from weak light nonlinear optics, ultrafast nonlinear optics to electro-optical theory and applications. In the past decade, nonlinear optics has evolved into many different branches, depending on the form of the material used for studying the nonlinear phenomena. The growth of research in nonlinear optics is closely linked to the rapid technological advances that have occurred in related fields, such as ultra-fast phenomena and optical communications. Nonlinear-optics activities range from the fundamental studies of the interaction between matter and radiation to the development of devices, components, and systems of tremendous commercial interest for widespread applications in optical telecommunications, medicine, and biotechnology. This book reviews the development of some nonlinear optics researches in China, not only the discovery of new principles, but also potential applications of nonlinear optics for various industries.

Book Description
The classic guide to a powerful technique that can increase your mindfulness and lead to personal transformation Based on groundbreaking research conducted at the University of Chicago, the focusing technique has gained widespread popularity and scholarly acclaim. It consists of six easy-to-master steps that identify and change the way thoughts and emotions are held within the body. Focusing can be done virtually anywhere, at any time, and an entire “session” can take no longer than ten minutes, but its effects can be felt immediately–in the relief of bodily tension and psychological stress, as well as in dramatic shifts in understanding and insight. In this highly accessible guide, Dr. Eugene Gendlin, the award-winning psychologist who developed the focusing technique, explains the basic principles behind focusing and offers simple step-by-step instructions on how to utilize this powerful tool for tapping into greater self-awareness and inner wisdom. As you learn to develop your natural ability to “focus,” you’ll find yourself more in sync with both mind and body, filled with greater self-assurance, and better equipped to make the positive changes necessary to improve and enhance every aspect of your life.

Book Description
From the best-selling author of The Wind-Up Bird Chronicle and After Dark, a rich and revelatory memoir about writing and running, and the integral impact both have made on his life. In 1982, having sold his jazz bar to devote himself to writing, Haruki Murakami began running to keep fit. A year later, he’d completed a solo course from Athens to Marathon, and now, after dozens of such races, not to mention triathlons and a slew of critically acclaimed books, he reflects upon the influence the sport has had on his life and—even more important—on his writing. Equal parts training log, travelogue, and reminiscence, this revealing memoir covers his four-month preparation for the 2005 New York City Marathon and includes settings ranging from Tokyo’s Jingu Gaien gardens, where he once shared the course with an Olympian, to the Charles River in Boston among young women who outpace him. Through this marvellous lens of sport emerges a cornucopia of memories and insights: the eureka moment when he decided to become a writer, his greatest triumphs and disappointments, his passion for vintage LPs and the experience, after the age of fifty, of seeing his race times improve and then fall back. By turns funny and sobering, playful and philosophical, What I Talk About When I Talk About Running is both for fans of this masterful yet guardedly private writer and for the exploding population of athletes who find similar satisfaction in distance running.

Book Description
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.
