Book Description
A model of the additive-pulse modelocked (APM) laser is developed, with an emphasis on nonlinear dynamics. The APM laser has been traditionally used as a stable, pulsed light source, with multiple regions of instability that hamper useful operation. Many of these instabilities are deterministic, resulting from large levels of nonlinearity, and can be exploited if understood. In this thesis, the different elements of a typical APM laser are studied, and their effects incorporated into a four-equation iterative model. The essentials of nonlinear dynamics are then presented, as tools for identifying and characterizing deterministic instabilities. The APM model is then used to simulate the laser under conditions of high non-linearity, giving rise to quasiperiodicity, period-doubling, crises, and chaos. The chaotic regions of operation are characterized by embedding dimension and largest lyapunov exponent, and some sample attractors are plotted in three dimensions. The identification of the period-doubling route to chaos, the Lyapunov exponent quantification of the chaos, and the proof of quasiperiodicity and crisis behavior all represent new accomplishments and valuable insight into the APM laser dynamics.

Book Description
A distinctive discussion of the nonlinear dynamical phenomena of semiconductor lasers. The book combines recent results of quantum dot laser modeling with mathematical details and an analytic understanding of nonlinear phenomena in semiconductor lasers and points out possible applications of lasers in cryptography and chaos control. This interdisciplinary approach makes it a unique and powerful source of knowledge for anyone intending to contribute to this field of research. By presenting both experimental and theoretical results, the distinguished authors consider solitary lasers with nano-structured material, as well as integrated devices with complex feedback sections. In so doing, they address such topics as the bifurcation theory of systems with time delay, analysis of chaotic dynamics, and the modeling of quantum transport. They also address chaos-based cryptography as an example of the technical application of highly nonlinear laser systems.

Book Description
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.
