Laser Physics $147.58 This book treats the interaction of radiation with matter, particular attention being paid to the laser. Knowledge is assumed of the usual halfyear introduction of quantum mechanics found in undergraduate physics curricula. The material can be covered in two semesters, or, alternatively, the first part (Chaps 113) can be used as a onesemester course in which quantum mechanical aspects of the electromagnetic field are ignored. Each chapter is accompanied by problems that illustrate the text and give useful (occasionally new) results. Existing laser media are intrinsically quantum mechanical and are most easily studied with the quantum theory. Understanding the laser along these lines enlivens ones understanding of quantum mechanics itself. In fact, the material constitutes a viable, applied alternative for the usual second and third semesters of quantum mechanics. Author: Sargent, Murry III/ Sargent, Murray/ Scully, Marian O.

Problems in Laser Physics $157.72 This book presents the first comprehensive collection of solved problems in laser physics covering both fundamental and applied aspects of laser science and technology. The framework of the book, including structuring of topics and notations, closely follows that adopted in the Principles of Laser book by Professor O. Svelto. The collection of problems presented in this book appears therefore a natural complement to Sveltos textbook for testing and developing the skills acquired in the reading of the theory; however, it may also be a useful support to any general textbook on laser physics, wherein problems are usually not solved in detail. We remark that this is, to our knowledge, the first book to provide a complete and satisfactory set of solved problems in such a highly developing field of science and technology. The problems fall mainly into three distinct categories: (i) numerical/applied problems, which help the reader to become confident and familiar with the basic concepts and methods of laser physics, and to acquire a feeling for numerical parameters entering in realworld laser systems; (ii) complementary problems, that present in detail demonstrations of some analytical parts not given in the textbook; and (iii) advanced problems, aimed either to provide a deeper understanding of the subject or to cover more recent developments in the field. Audience: This book is primarily intended for undergraduate and graduate students in physics, engineering, and chemistry. However, it may also be a useful tool for industrial professionals working in the field of laser technologies and laser applications, as well as for researchers interested in basic aspects of realworld lasers and related fields. Author: Cerullo, Giulio/ Nisoli, Mauro/ Longhi, Stefano Binding Type: Paperback Number of Pages: 308 Publication Date: 2001/10/31 Language: English Dimensions: 9.24 x 7.16 x 0.85 inches |

Laser Physics (Hardcover) $416.83 In Laser Physics the interaction of radiation and matter, and the principles of laser operation are treated at a level suitable for fourth-year undergraduate courses or introductory graduate courses in physics, chemistry or engineering. The factors which determine efficiency, wavelength coverage, output power, and beam quality of the different classes of laser are treated both in terms of fundamental theory and practical construction aspects. Details of established types of solid-state, semiconductor, and gas lasers are examined together with the techniques that enable their output to be converted widely across the spectrum. The latest advances in high power fibre lasers, femtosecond lasers, and X-ray lasers are explained. The text is liberally illustrated with more than 300 diagrams. An extensive bibliography is provided, together with numerical problems in each chapter. Solutions are available via the web. |

Strong Field Laser Physics $360.72 Due to the rapid progress in laser technology a wealth of novel fundamental and applied applications of lasers in atomic and plasma physics have become possible. This book focuses on the interaction of high intensity lasers with matter. It reviews the state of the art of high power laser sources, intensity laseratom and laserplasma interactions, laser matter interaction at relativistic intensities, and QED with intense lasers.

Physics of Solid State Laser Materials $135.33 This graduatelevel text presents the fundamental physics of solidstate lasers, including the basis of laser action and the optical and electronic properties of laser materials. After an overview of the topic, the first part begins with a review of quantum mechanics and solidstate physics, spectroscopy, and crystal field theory; it then treats the quantum theory of radiation, the emission and absorption of radiation, and nonlinear optics; concluding with discussions of lattice vibrations and ionion interactions, and their effects on optical properties and laser action. The second part treats specific solidstate laser materials, the prototypical ruby and NdYAG systems being treated in greatest detail; and the book concludes with a discussion of novel and nonstandard materials. Some knowledge of quantum mechanics and solidstate physics is assumed, but the discussion is as selfcontained as possible, making this an excellent reference, as well as useful for independent study.
