Book Description
Organic lasers are broadly tunable coherent sources, potentially compact, convenient and manufactured at low-costs. Appeared in the mid 60’s as solid-state alternatives for liquid dye lasers, they recently gained a new dimension after the demonstration of organic semiconductor lasers in the 90's. More recently, new perspectives appeared at the nanoscale, with organic polariton and surface plasmon lasers. After a brief reminder to laser physics, a first chapter exposes what makes organic solid-state organic lasers specific. The laser architectures used in organic lasers are then reviewed, with a state-of-the-art review of the performances of devices with regard to output power, threshold, lifetime, beam quality etc. A survey of the recent trends in the field is given, highlighting the latest developments with a special focus on the challenges remaining for achieving direct electrical pumping of organic semiconductor lasers. A last chapter covers the applications of organic solid-state lasers.

Book Description
This unique book provides an overview of the principle and applications of lasers enriched with numerous illustrations.Being over fifty years old, lasers continue to amaze us. Their performance characteristics are constantly reaching new limits, and the scope of their applications continues to expand. Yet, it took years of effort by teams of physicists to transform the fundamental notions of Einstein into the first experimental beam of laser light. And history is still going on as fundamental research is now triggered by its remarkable properties.This book addresses every aspects of laser light, from its fundamental principles to its industrial applications, at a level particularly suited for high school teachers, students, and anybody curious about science and technology.

Book Description
By the time of his death, Herve Guibert had become a singular literary voice on the impact of AIDS in France. He was prolific. His oeuvre contained some twenty novels, including To the Friend Who Did Not Save My Life and The Compassion Protocol. He was thirty-six years old. In Cytomegalovirus, Guibert offers an autobiographical narrative of the everyday moments of his hospitalization because of complications of AIDS. Cytomegalovirus is spare, biting, and anguished. Guibert writes through the minutiae of living and of death—as a quality of invention, of melancholy, of small victories in the face of greater threats—at the moment when his sight (and life) is eclipsed. This new edition includes an Introduction and Afterword contextualizing Guibert’s work within the history of the AIDS pandemic, its relevance in the contemporary moment, and the importance of understanding the quotidian aspects of terminal illness.

Book Description
Over the last few years, there has been a convergence between the fields of ultrafast science, nonlinear optics, optical frequency metrology, and precision laser spectroscopy. These fields have been developing largely independently since the birth of the laser, reaching remarkable levels of performance. On the ultrafast frontier, pulses of only a few cycles long have been produced, while in optical spectroscopy, the precision and resolution have reached one part in Although these two achievements appear to be completely disconnected, advances in nonlinear optics provided the essential link between them. The resulting convergence has enabled unprecedented advances in the control of the electric field of the pulses produced by femtosecond mode-locked lasers. The corresponding spectrum consists of a comb of sharp spectral lines with well-defined frequencies. These new techniques and capabilities are generally known as “femtosecond comb technology. ” They have had dramatic impact on the diverse fields of precision measurement and extreme nonlinear optical physics. The historical background for these developments is provided in the Foreword by two of the pioneers of laser spectroscopy, John Hall and Theodor Hänsch. Indeed the developments described in this book were foreshadowed by Hänsch’s early work in the 1970s when he used picosecond pulses to demonstrate the connection between the time and frequency domains in laser spectroscopy. This work complemented the advances in precision laser stabilization developed by Hall.

Book Description
A comprehensive overview of the principles and applications of femtosecond lasers, especially applied to medicine and to production technology. The advantages and problems of ultrashort laser pulses are discussed in more detail in the context of applications in the micro-machining of technical materials such as drilling, surface structuring and cutting, in medical use like dental, ophthalmologic, neurological and otolaryngological applications, in metrology, and in the generation of x-rays. Safety aspects are also considered.

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.

Book Description
Recent years have witnessed rapid advances in the development of solid state, fiber, semiconductor, and parametric sources of coherent radiation, which are opening up new opportunities for laser applications. Laser Sources and Applications provides a tutorial introduction to the basic principles of these developments at a level suitable for postgraduate research students and others with a basic knowledge of lasers and nonlinear optics. Encompassing both the physics and engineering aspects of the field, the book covers the nature of nonlinear optical interactions; solid state, fiber, and semiconductor lasers; optical parametric oscillators; and ultrashort pulse generation and applications. It also explores applications of current interest, such as electromagnetically induced transparency, atomic trapping, and soliton optical communications.

Book Description
Expensive, delicate, and difficult to operate, femtosecond lasers have already won two Nobel Prizes and created multi-billion dollar industries. As these lasers break out of laboratories for use in real-world large-scale applications, the number of people using them increases. This book provides a fresh perspective on femtosecond lasers, discussing how they are soon to become a universal light source, spanning any timescale and generating any wavelength of light. Starting from the basics of light itself, this book presents in an everyday manner, with clear illustrations and without formulas, what makes this class of lasers so versatile and the future of many more applications. Many of the subjects covered in this book are described in plain words for the first time.
