TLDR
Using generalized Ginzburg-Landau equations derived recently, the authors solved the laser equations analytically for the case of spontaneous ultra-short laser pulses and compared their results with previous computer solutions by Risken and Nummedal.About:

Non-equilibrium Transitions in Sub/Second Harmonic Generation
TL;DR: In this article, a non-linear optical system with a mode coupled to its second harmonic, exhibiting a rich variety of non-equilibrium steady-state transitions is analyzed, and a semiclassical analysis is used to examine the steady states and their stability, and thus predict the existence of various instabilities.

Theory of Optical Bistability
TL;DR: In this paper, the authors consider a c-w laser beam which is injected into a resonant cavity tuned or nearly tuned to the incident light, where the incident beam is partially transmitted, partially reflected and partially scattered by the cavity.

The real and complex Lorenz equations in rotating fluids and lasers
John Gibbon,Mark McGuinness +1 more
TL;DR: The Lorenz equations are derived systematically from amplitude equations of weakly nonlinear dispersively unstable physical systems near criticality when weak dissipation is added as discussed by the authors, and they are only valid if the undamped neutral curve is not destabilised by the addition of weak dispersive effects.
Journal ArticleDOI
Coherent manipulations of atoms using laser light
TL;DR: In this paper, the authors present basic concepts of quantum states, of laser radiation and of the Hilbert-space state vector that provides the theoretical portrait of probability amplitudes, the tools for quantifying quantum properties not only of individual atoms and molecules but also of artificial atoms and other quantum systems.

Overview of instabilities in laser systems
TL;DR: In this article, a brief overview of the main types of instability in laser systems is presented, including the early spiking in solid-state lasers, single-mode lasers with homogeneous and inhomogeneous broadening, the effect of noise and modulation, multimode operation, and a brief survey of nonlinear dynamics.

Cooperative phenomena in systems far from thermal equilibrium and in nonphysical systems
TL;DR: In this article, a tutorial approach to cooperative phenomena in systems far from thermal equilibrium and in non-physical systems is presented, with particular emphasis on the question of how order and self-organization may arise.

FM and AM mode locking of the homogeneous laser - Part I: Theory
D. Kuizenga,Anthony E. Siegman +1 more
TL;DR: In this article, a complex Gaussian pulse is followed through one pass around the laser cavity to keep the pulse Gaussian, and the analysis is further extended to include effects of detuning of the modulator, in which case analytical expressions are obtained for the phase shift of the pulse within the modulation cycle, the shift of pulse spectrum off line center, the change in pulse length, and change in power output.

Self‐Pulsing in Lasers
H. Risken,K. Nummedal +1 more
TL;DR: In this paper, the origin of pulse formation in laser is investigated in terms of a homogeneously broadened, two-level ring laser model, and a simple approximate equation is derived, by which most of the features of the final pulse are given analytically.

Quantum theory of light propagation in a fluctuating laser-active medium
R. Graham,Hermann Haken +1 more
TL;DR: In this paper, the propagation of an electromagnetic field in a fluctuating laser-active medium is described by two-level atoms which are embedded in a merely passive solid matrix and homogeneously distributed over space.

Irreversible Circulation of Fluctuation
Kazuhisa Tomita,Hiroyuki Tomita +1 more
TL;DR: In this article, a macroscopic orbital revolution may appear, which is characteristic to far from equilibrium situation, when it entails instability, and cyclic balance is useful in describing coupled degrees of freedom at off-equilibrium situation.
