Available in PDF, EPUB and Kindle. Book excerpt: This book gives the readers an introduction to experimental and theoretical knowledge acquired by large-scale laser laboratories that are dealing with extra-high peak power and ultrashort laser pulses for research of terawatt (TW), petawatt (PW), or near-future exawatt (EW) laser interactions, for soft X-ray sources, for acceleration of particles, or for generation of hot dense thermal plasma for the laser fusion. The other part of this book is dealing with the small-scale laser laboratories that are using for its research on commercial sources of laser radiation, nanosecond (ns), picosecond (ps), or femtosecond (fs) laser pulses, either for basic research or for more advanced applications. This book is divided into six main sections dealing with short and ultrashort laser pulses, laser-produced soft X-ray sources, large-scale high-power laser systems, free-electron lasers, fiber-based sources of short optical pulse, and applications of short pulse lasers. In each chapter readers can find fascinating topics related to the high energy and/or short pulse laser technique. Individual chapters should serve the broad spectrum of readers of different expertise, layman, undergraduate and postgraduate students, scientists, and engineers, who may in this book find easily explained fundamentals as well as advanced principles of particular subjects related to these phenomena.

Available in PDF, EPUB and Kindle. Book excerpt: The Lawrence Livermore National Laboratory (LLNL) has a long history of developing high power lasers for use in basic science and applications. The Laser Science and Technology Program (LS & T) at LLNL supports advanced lasers and optics development both for the National Ignition Facility (NIF) as well as for high power lasers and optics technology for a broader range of government, military and industrial applications. The NIF laser is currently under construction with the first of the 192 beamlines being activated. When finished NIF will have an output energy of 2 MJ at 351 nm. This system will be used for studies of high energy density physics, equation of state and inertial confinement fusion. It is now generally acknowledged that the future of laser missile defense lies with solid state lasers. The leading laser technology for theater missile defense is under development within the LS & T and funded by the US Army SMDC. This high average power technology is based on a solid state laser operated in a heat capacity mode. In the concept the heat producing lasing cycle is separated in time from the cooling cycle thus reducing thermal gradients and allowing significantly greater average output power. Under the current program, an LLNL developed laser has achieved a record setting 13 kW of average power in 20 second duration bursts. We have also performed target lethality experiments showing a previously unrecognized advantage of a pulsed laser format. The LLNL work is now focused on achieving improved output beam quality and in developing a 100 kW output with diode pumping of a large aperture crystal gain medium on a compact mobile platform. The Short Pulse Laser Group of LS & T has been developing high power short pulse laser systems for a number of applications. Of great importance is petawatt (10{sup 12} Watt) and greater power output to support experiments on the NIF. We are developing a system of 5 M class output and 5 to 10 ps pulse duration for generating intense radiation for radiography, particle beam generation and eventually for a new class of fusion experiments call fast ignition. We have also built a record setting 50 watts of average output from a picosecond class laser and are using this technology for materials processing such as fine hole drilling and safe cutting of munitions. The laser science and technology program has developed and deployed a laser guide star on the Lick telescope on Mt. Hamilton and most recently on the Keck telescope in Hawaii. Our current development work in this area is focused on developing a much more compact all solid state diode pumped laser fiber system. Finally in a program originally initiated by DARPA we have developed a phase conjugated Nd:glass laser system with record setting performance and successfully deployed it for Navy and Air Force satellite imaging applications and have more recently successfully transferred it to industry for use in an emerging technology called laser peening. This laser technology is capable of 25 J to 100 J per pulse, 10 ns to 1000 ns pulse duration, 5 Hz laser. The technology has been industrially deployed and is proving to be highly effective in generating high intensity shocks that induce compressive residual stress into metal components. The compressive stress retards fatigue and stress corrosion cracking and is proving to extend the lifetime of high value components by factors of ten. This processing adds lifetime, enhances safety and can improve performance of aircraft systems. Laser peening is now being evaluated to reduce the weight of aircraft and may play a major role in the future combat system and its air transport by enabling lighter craft, longer range and greater payload. The laser peening technology is also being moved forward in NRC license application as the means to eliminate stress corrosion cracking for Yucca Mountain nuclear waste disposal canisters as well as a broad range of other applications.

Available in PDF, EPUB and Kindle. Book excerpt: The second International Conference on Trends in Quantum Electron ics (TQE'85) was held in Bucharest at the National Centre for Physics in September 1985, and brought together more than 350 scientists from 22 countries. In accordance with the objectives established at the first conference, which was held in 1982 in conjunction with the third International Summer School in Coherent Optics, the second conference con centrated upon the central topics and chief directions of development in quantum electronics - which stands out as an area of science and technology that is currently expanding vigorously. On the other hand, it was also apparent that TQE'85 was primarily influenced by the worldwide celebration, in 1985, of the 25th anniversary of the laser - a moment of prime importance in the development of many frontline fields, including communications, chemistry, biology, health care and materials processing. A special session was devoted to this anniversary. In keeping with the dynamic spirit of the conference, the fine quality of the invited lectures and the other contributions set a high scientific standard for the proceedings. Mention should be made of the posters that were presented throughout the conference. These, together with the exhibition of books and journals and a display of specialized scientific equipment, did much to create a framework for effective communication and stimulating interaction, to the benefit of all the participants. Of invaluable help in the preparation of the conference was the collaboration of the International Scientific Advisory Committee.

Available in PDF, EPUB and Kindle. Book excerpt: Optical pulses are flashes of light, which are often generated with lasers (laser pulses) and delivered in the form of laser beams. Due to the enormously high optical frequencies, optical pulses can be extremely short (ultrashort) when their optical bandwidth spans a significant fraction of the mean frequency. Pulsed operation of lasers refers to any laser not classified as continuous wave, so that the optical power appears in pulses of some duration at some repetition rate. This encompasses a wide range of technologies addressing a number of different motivations. Some lasers are pulsed simply because they cannot be run in continuous mode. In other cases the application requires the production of pulses having as large an energy as possible. Since the pulse energy is equal to the average power divided by the repetition rate, this goal can sometimes be satisfied by lowering the rate of pulses so that more energy can be built up in between pulses. In laser ablation for example, a small volume of material at the surface of a work piece can be evaporated if it is heated in a very short time, whereas supplying the energy gradually would allow for the heat to be absorbed into the bulk of the piece, never attaining a sufficiently high temperature at a particular point. Other applications rely on the peak pulse power (rather than the energy in the pulse), especially in order to obtain nonlinear optical effects. For a given pulse energy, this requires creating pulses of the shortest possible duration utilising techniques such as Q-switching. This book discusses aspects of laser pulses generation, characterisation, and practical applications. Some new achievements in theory, experiments, and design are demonstrated. This book will be useful for engineers and managers, for professors and students, and for those who are interested in laser science and technologies.

This book was released on 2012-12-06 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the introduction of balloon angioplasty for the relief of coronary artery stenoses and of anginal symptoms in patients with coronary artery disease by Andreas Griintzig in 1977, the field of interventional technology and treatment strategies has grown enormously. For the reduction of hemodynamically significant coronary artery stenoses balloon angioplasty is the standard and reference method with a high primary success and low complication rate. Because of the relatively high recurrence rates of 30-40% of balloon angioplasty a whole family of different angioplasty techniques has been developed since then. Among those are atherectomy devices, laser angioplasty, radiofrequency angioplasty, high and low speed rotational angioplasty and stenting of stenosed vessels. Balloon angioplasty has been extended to aortic and mitral valve stenoses, and supraventricular and ventricular tachycardias can now be treated by catherter ablation techniques. In 1989 an International Symposium on standard and newer inter ventional techniques has been held at the University of Ulm. This volume contains the essential parts and presentations of the international faculty of experts in the field. In four chapters the principles, advantages, pitfalls and future developments of coronary angiopiasty, angioplasty of peripheral arteries, balloon valvuloplasty and of catheter ablation of supraventricular and ventricular tachycardias are described in detail. We hope that this 'State-of-the-Art' representation will be of great value for both the non expert reader and the active researcher in the fields addressed within the book. V. Hombach, M.
