Book Description
Chemical and Biochemical Applications of Lasers, Volume IV focuses on the practical applications of standard commercial laser systems. This book examines the structural studies of DNA by fluorescence microscopy and discusses photochemistry and structural spectroscopy. Organized into eight chapters, this volume starts with an overview of a few cases of laser-induced fluorescence studies of biological molecules. This text then examines the sharp fluorescence spectra of complex molecules in solids that are obtained when a narrow-band laser selectively excites molecules in particular sites. Other chapters describe the theory and application of resonance Raman spectroscopy to various biological systems. This book provides as well a thorough treatment of coherent anti-Stokes Raman spectroscopy and its application in combustion diagnostics and analytical chemistry. The final chapter explores laser control of the sequential photochemical reaction of the drug psoralen with the two strands of the DNA double helix. Physicists, chemists, electrochemists, and chemical engineers will find this book useful.

Book Description
Chemical and Biological Applications of Lasers, Volume V focuses on the laser applications in photochemistry and spectroscopy. This book examines the spectroscopic detection of single atoms and explores the purification of industrial chemicals. Organized into seven chapters, this volume starts with an overview of the methods developed for laser detection of single atoms, including fluorescence, photoionization, photodeflection, and their combinations. This text then discusses the methods of high resolution spectroscopy, which provide detailed information on molecular structure and reaction kinetics studies. Other chapters review several laser photodissociation studies, which explain dissociation dynamics. This book discusses as well the possibilities for selective photochemical reactions and examines the potential of lasers for practical application in chemical processing. The final chapter considers the various metals that can undergo a photochemical change in oxidation state in ordinary solvents. This book is a valuable resource for physicists, chemists, electrochemists, photochemists, electrical engineers, and chemical engineers.

Book Description
This second edition, appearing about twenty years after the discovery of the laser is a substantially revised version of the first edition. It is, like the first, aimed at both classroom teaching and self-study by technical personnel interested in learning the principles of laser operation. In preparing the second edition the hope has been that both these aims will be better served as a result of the various improvements made. The main changes have been made with the following aims in mind: (i) To update the book. Thus new topics have been added (in particular on various new types of lasers, e. g. , rare-gas-halide excimer lasers, color-center lasers, and free-electron lasers), while on the other hand some topics have been given less emphasis (again this applies particularly to some types of lasers, e. g. , the ruby laser). Updating is especially important in the area of laser applications, and the chapter on this topic has therefore been com pletely rewritten. (ii) To make some improvements to the logical consis tency of the book by rearranging material and adding new material. Thus a few topics have been moved from one section to another and a new chapter entitled Laser Beam Transformation has been added. (iii) To further reduce the mathematical content, placing greater emphasis on physical descrip tions of phenomena.

Book Description
Based on a symposium on lasers, molecules, and methods held at the Los Alamos Center for Nonlinear Studies held in July 1986. Contributors present recent advances in theoretical and experimental research on a diversity of dynamical and optical phenomena resulting from the interactions of laser beams with molecules. They describe the predictive results of sophisticated mathematical models, the equipment involved in experiments, and reveal new insights into molecular structure and behavior.

Book Description
This Conference on biomedical applications of. lasers ~Ias organized by the Quantum Electronics Divisional Board of the European Physical Society (E.P.S.) and held at the Villa of Poggio Imperiale in Florence, September 3-6, 1979. As kno~m, laser surgery (especially microsurgery and endoscopic photo coagulation) has recently made important progress, and the field is expand i ng rapidly. Very significant applications of lasers have also been achieved in Bi ology during recent years (cell microsurgery, cell counting and sorting, cytofluorimeter devices, etc.) and the potential of laser techniques in this field is nO~1 sufficiently well establ ished. A new class of applications of laserradiJtion in Medicine has recently been made possible by important results obtained with low intensity (non coagulative) visible lasers, such as photodynamic therapy of tumors. At the same time important branches of Medicine, where light effects are studied and optical techniques are presently used for a certain number of clinical applications, such as dermatology and pediatry, appear to be still in their infancy as far as the proper use of optical radiation and techniques, and the understanding of fundamental photoinduced biological processes are con cerned. Moreover, laser photobiology appears a very promising field for the investigation of fundamental processes at the biomolecular level.

Book Description
Lasers and chemical change is the study of radiation and molecules in dis equilibrium. The distinguishing feature of such systems is the extreme de parture from thermal equilibrium: the radiation is usually confined to a narrow frequency range, is well coll imated, and is far brighter than black body radiation; the chemical composition and also the distribution of mole cules over their different energy states are often markedly displaced from that expected at equilibrium. Such systems can be used as a source of laser radiation and, reversedly, lasers can rapidly and selectively displace mole cular systems from equilibrium. The subsequent evolution of the initially prepared state can then be monitored - again using lasers. One purpose of this book is to introduce the concepts required to d- cuss systems of radiation and molecules in disequilibrium. These include the physics of (laser) radiation and of radiation-matter interaction and molecular structure and spectroscopy. Excellent textbooks of these topics are available and our survey (in Chap. 3) is only intended to accent the es sential points, with special reference to atomic and molecular radiation physics. Considerably more attention is given to the topic of disequilibrium in chemical systems (Chap. 2). In particular we consider both inter- and intra molecular dynamics with special reference to energy requirements and energy disposal in chemical reactions and to what goes on in between - intramole cular energy migration.

Book Description
The International Conference on Lasers and Applications was held in Rio de Janeiro, Brazil from 29 June to 3 July 1980. This conference was held to commemorate the memory of Professor Sergio Porto who died suddenly about one year earlier while attending a laser conference in the Soviet Union. The sub ject matter covered the active areas of laser devices, photochemistry, non linear optics, high-resolution spectroscopy, photokinetics, photobiology, photomedicine, optical communication, optical bistability, and Raman spec troscopy. The conference was attended by over 150 people including scientists from Japan, France, England, West Germany, Norway, Italy, Brazil, Chile, Argentina, India, Canada, and the United States. Amemorial session attended by members of the Porto family and ranking Brazilian government dignitaries preceded the start of the conference. The location of the conference in Rio de Janeiro, Brazil, was chosen be cause it was in the homeland of Sergio Porto and provided an opportunity for his friends, colleagues, and countryrnen to pay hornage to hirn. The setting on Copacabana Beach afforded access to the lovely beaches, restaurants, and nightlife of one of the most beautiful and exciting cities of the world. There were tours of the city together with a banquet that featured a performance by one of the best Samba Schools in Rio. Financial support from many sponsors in Brazil and the United States is gratefully acknowledged in making this working conference a fitting tribute to the memory of Professor S.P.S. Porto.
