Book excerpt: This monograph summarizes major achievements in laser dynamics over the past three decades. The book begins with two introductory Chapters. Chapter 1 offers general considerations on quantum oscillators, formulates the requirements for the laser key elements and shows how these requirements are met in different laser systems. The second Chapter proposes the mathematical models used in semiclassical laser theory, discusses the approximations and simplifications in particular cases, and specifies the range of applicability of these models. In Chapters 3-5 attention is given primarily to the steady states and their stability, the laser behavior in the instability domain, the characteristics of regular and chaotic pulsations and the nature of their mechanisms. Chapter 6 deals with the processes in a laser, accompanying the time variance of laser parameters. Considerable attention is given to a laser response to weak, low-frequency modulation of the parameters. The problems addressed therein are resonant modulation enhancement, transition to the nonlinear regime, chaotic response to periodic impact, spike-like generation due to variation of the cavity geometry and a laser rod temperature drift. Laser behavior is subject to qualitative changes if its optical elements exhibit nonlinear properties. The action of a saturable absorber, which leads to a loss of laser stability and provides passive Q-modulation, is investigated. To a much lesser degree the researchers' attention has been attracted by other nonlinear effects such as self-focusing, e.g., which may have a strong influence on laser dynamics. All of these issues are covered in Chapter 7. The book is intended for researchers, engineers, graduate and post-graduate students majoring in quantum electronics.

Available in PDF, EPUB and Kindle. Book excerpt: Principles of Lasers and Optics, first published in 2005, describes both the fundamental principles of the laser and the propagation and application of laser radiation in bulk and guided-wave components. All solid state, gas and semiconductor lasers are analysed uniformly as macroscopic devices with susceptibility originated from quantum mechanical interactions to develop an overall understanding of the coherent nature of laser radiation. Analyses of the unique properties of coherent laser light in bulk and guided-wave components are presented together and derived from fundamental principles, to allow students to appreciate the differences and similarities. Topics covered include discussions on how laser radiation should be analysed, the macroscopic differences and similarities of various analyses, special techniques, types of lasers and setting up laser analyses. This text will be useful for first-year graduates in electrical engineering and physics and also as a reference book on analytical techniques.

This book was released on 2008-01-01 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: After the first time chaos could be controlled, for the last quarter of century, a diversity of publications have been devoted to the development of new control schemes and their applications to different laser systems. This book assembles several review papers which analyze and describe the most important achievements in controlling laser dynamics and synchronization of laser systems. The papers report a variety of interesting dynamical phenomena encountered in different types of lasers and related to control techniques. For the last 20 years laser physics and nonlinear dynamics have undergone a crucial progress. Understanding lasers as dynamical systems involves concepts associated mostly with the nonlinear nature of these systems. Since the appearance of the pioneering work of E. Ott, C. Grebogi and J. A. Yorke in 1990, who proposed a method for controlling chaos, active attempts for applying this method and other control methods to laser systems have been conducted. Many research works were directed not only to the observation and identification of dynamical regimes in lasers, but also to control laser dynamics and chaos. Considerable progress has been made in research and development of semiconductor and fiber lasers. The special interest these lasers stir up is explained by their easy operation, small size, low price, and, of course, their successful application in communications. However, in spite of the huge progress in laser physics and nonlinear dynamics, only few reviews have been devoted to this topic. The book has an interdisciplinary character because the topic of this book is a great mixture of four big areas of science: laser physics, nonlinear dynamics, control theory, and synchronization. Each area was developed independently till the first nonlinear control of laser dynamics has been realized. The aim of this book is to address a broad readership: students, researchers, engineers, technicians, who work with lasers, as well as scientists conducting interdisciplinary research; it is intended for both theoreticians and experimentalists. The intention of this book is to give the reader a good understanding of nonlinear laser dynamics, not only in one specific type of laser but rather in many different types of lasers, as each control method or coupling is introduced. Four chapters of the book are devoted to laser dynamics control and describe the most important achievements of the last two decades in this topic. These chapters review already classical and relatively new results on stabilizing unstable periodic orbits in chaotic lasers and other control methods providing the reader with an extensive bibliography. The book also contains four chapters devoted to synchronization of coupled lasers. Special attention in the book is given to experimental applications of different control methods and synchronization phenomena in different laser systems. Editing this book has been a rewarding experience for me. Since 1979, I have been associated with lasers, beginning as a postgraduate student at the Institute of Physics of the Belarus Academy of Sciences in Minsk when I helped build a CO2 laser for a research project under Professor Vladimir V. Churakov direction. He was the first person to instil in me an enthusiasm for optics and light. I then was very fortunate to do my thesis work under supervision of Academician of the Byelorussian Academy of Sciences Boris Ivanovich Stepanov, who encouraged me to reduce ideas to simple concepts. Being very diligent, he nonetheless, also was a cheery person. He used to say that a real scientist has to work more than 24 hours per day, write monographs and must never stay too much time in one research area, but should change direction from time to time. I also thank Dr. Boris F. Kuntsevich for helping me to understand the fundamental theory of laser oscillations. At that time, in the late 70s - early 80s, since there were no personal computers we had to search for analytical solutions of laser equations. This was a good exercise to learn the foundation of laser physics. I am grateful to my colleagues Drs. Vladimir O. Petukhov and Ivan M. Bertel, who played a key role in my experimental practice helping me to install and equip my first experimental setup. Being a part of a stimulating group of young researchers at the Laboratory of General Spectroscopy during the growth of the field of laser spectroscopy was an unparalleled opportunity. We built CO2 lasers and tried to stabilize them for spectroscopy applications. For a long period of time Dr. Viacheslav N. Chizhevsky and I worked together, he got me involved in the world of chaos and helped me take my first steps into numerical simulations with MATLAB; together we carried out many experiments with CO2 lasers. He shared his ideas with me and I deeply appreciate all our fruitful discussions. Back then, we thought (about) laser was a stable device and treated any instabilities and chaos as a consequence of mechanical vibrations or bad alignment. It was only in 1964 that the Russian physicists A. Z. Grazyuk and A. N. Oraevskii found in numerical studies of the equations describing a simplest (homogeneously broadened, single-mode, traveling wave, resonantly tuned) laser, a time-dependent solution that consisted of pulses, varying irregularly with time. They even used at that time the term chaotic to describe this irregular pulsing behavior. Laser dynamics stagnated in a rudimentary state for more than one decade until in 1975, when the German theoretical physicist G. Haken concluded, from the isomorphy of a laser with Lorenz equations, that lasers could exhibit a non-periodic, pulsing emission, that is a chaotic emission. Even though, in the early 80s we did not believe that the Lorenz-Haken instability was inherent to real laser systems; thinking it was only an academic curiosity invented by theoreticians far removed from the daily reality of experimental laser physics, nonlinear laser dynamics was born and in 1982 after the first clear experimental evidence of laser chaos, was baptized by F. T. Arecchi These results, sharpening the perception of lasers as unstable systems, were then followed by a large number of experimental and theoretical investigations. Many researchers tried to exploit the new acquired knowledge of laser dynamics in some applications. Even though, the principal aim was still focused on avoiding instabilities to obtain a stable laser emission. Curiously, we had observed chaos in a bidirectional ring CO2 laser long before it was discovered by Prof. Arecchi's group. However, we did not pay serious attention to these findings, thinking it was the same chaotic behavior that had been previously observed in solid-state lasers. Moreover, we could not even publish our results in public scientific journals because in the Soviet Union of the 80's, during the period of Cold War, laser subjects were classified as top secret and not even the word laser was allowed to be used in open scientific literature. To evade this ban and get permission to publish our results, we had to replace the word laser by synonym words optical quantum generator . Many scientists who dealt with lasers were not allowed to go abroad and participate in international conferences. I was mainly a laser experimentalist until 1997, when I went to Canada with my own means to participate in the Summer School on Nonlinear Dynamics in Biology and Medicine organized by Leon Glass and Michael C. Mackey at McGill University in Montreal, where we took very useful lectures and practical exercises on theoretical modeling of physiological systems. Thanks to these lectures I came to realize that the world obeys universal dynamical laws, and also discovered for myself that many phenomena observed in lasers are present in a wide class of dynamical systems. This instilled in me the idea that a laser can serve as a very useful instrument to elaborate new methods for controlling nonlinear dynamics and chaos, which can be applied then to other systems, including biological and medical ones. Professor Arecchi and coworkers developed the same idea in their recent works; they do mention such similarity in the first chapter of this book. During the economically difficult period of the perestroika many scientists from the former Soviet Union had to abandon science and either go work for the industry or establish their own business. Some of the science-loving researchers who yet insisted on working at universities and research institutes had to paint roofs and towers or buy and resell things in order to survive. Many of us were looking for a job abroad. I was very fortunate to be invited first in 1992 by Professor Michel Herman from Physical Chemistry Laboratory at the University of Brussels where I spent three months working with dye lasers and fast Fourier spectroscopy. Then, thanks to Professor Ramón Corbalán who invited me to create the Laboratory of Infrared and Far Infrared Lasers at Universitat Autónoma de Barcelona, I spent almost seven years in Spain, where we carried out a series of interesting experiments on laser dynamics control. During that period I was happy to visit other universities and laser laboratories, such as the laboratory of Professor Pierre Glorieux at Université de Lille (France) and Professor Fortunato Tito Arecchi at Institute de Ottica Applicata in Florence (Italy), where we carried out several collaborative experiments with CO2 lasers. I also thank Professor Ari Olafson for the kind hospitality he extended to me in Reykjavik where I spent four unforgivable months in 1996 working at the University of Iceland. Finally, to round out my scientific carrier I was invited to Mexico in 1999 where I presently work as a Research Professor at Centro de Investigaciones en Optica in Leon, Guanajuato. I wish to thank Dr. Vicente Aboites, physicist and philosopher, for his kind invitation. Although the laser technology in Mexico is not yet advanced, the government is making a great effort to help develop national laser science and technology. I thank CONACYT (National Council for Science and Technology) for partial support of the publication of this book through project No. 46973-E, in particular, and research on lasers and applications, in general. Working in the field of lasers and nonlinear dynamics at several different institutions has provided me with a broad perspective that I hope has successfully contributed to the manner in which many of the concepts are presented in this book. I thank all of the authors who contributed to this book and to the reviewers who worked under great time pressure to complete the reviewing process in a relatively short time. I sincerely hope this book will stimulate new discussions and fundamental issues to a deeper level of understanding of laser dynamics and to develop new approaches to control and synchronization of laser systems. The results of this exercise could be also useful on the definition of scientific and technological programs related to this topic.

Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to develop a unified approach to nonlinear science, which does justice to its multiple facets and to the diversity and richness of the concepts and tools developed in this field over the years. Nonlinear science emerged in its present form following a series of closely related and decisive analytic, numerical and experimental developments that took place over the past three decades. It appeals to an extremely large variety of subject areas, but, at the same time, introduces into science a new way of thinking based on a subtle interplay between qualitative and quantitative techniques, topological and metric considerations and deterministic and statistical views. Special effort has been made throughout the book to illustrate both the development of the subject and the mathematical techniques, by reference to simple models. Each chapter concludes with a set of problems. This book will be of great value to graduate students in physics, applied mathematics, chemistry, engineering and biology taking courses in nonlinear science and its applications.

Available in PDF, EPUB and Kindle. Book excerpt: The invention ofthe laser 25years ago resulted in powerfullight sources which led to the observation of unexpected and striking phenomena. New fields of science such as holography and nonlinear optics developed constituting the basis of this volume. The classical principle of linear superposition of light wavesdoes not hold anymore. Two laser beams crossing in a suitable material may produce a set of new beams with different directions and frequencies. The interaction of light waves can be understood by considering the optical grating structures which develop in the overlap region. The optical properties of matter become spatially modulated in the interference region of two light waves. Permanent holographic gratings have been produced in this way by photographic processes for many years. In contrast, dynamic or transient gratings disappear after the inducing light source, usually a laser, has been switched off. The grating amplitude is controlled by the light intensity. Dynamic gratings have been induced in a large number ofsolids, liquids, and gases, and are detected by diffraction, 'forced light scattering' of a third probing beam, or by self-diffraction of the light waves inducing the grating. The combined interference and diffraction effect corresponds to four-wave mixing (FWM) in the language of nonlinear optics. The process is called degenerate ifthe frequenciesofthe three incident wavesand the scattered wave are equal. Degenerate four-wave mixing (DFWM) is a simple method to achieve phase conjugation, i.e. to generate a wave which propagates time reversed with respect to an incident wave.
