摘要

本文从理论和实验两方面研究了具有调制损耗的B类激光器的动力学行为。我们将注意力集中在扫描调制频率时系统的响应上。系统的非线性导致激光强度在共振、共振次谐波和共振次谐波处具有多重稳定性。一般说来，伴随低耗散的次谐波和次谐波共振是非线性动力系统多稳定性的根源。我们展示了低调制幅值时的响应强度。我们证明了在系统的次谐波共振处调制频率的谐波产生。实验结果与该类型激光器最简单的动力学模型的数值结果吻合得很好。

Garden of bifurcating paths in a nonlinear optical system

We study both theoretically and experimentally the dynamical behavior of a Class B laser with modulated losses. We focus our attention on the response of the system as we sweep the modulation frequency. The nonlinearity of the system introduces a multistability of the laser intensity at resonance but also at subharmonics of the resonance and at harmonics of it. In general subharmonics and harmonics resonances in conjunction with low dissipation are at the origin of multistability in nonlinear dynamical systems. We show the response in intensity for low values of the modulation amplitude. We put in evidence the generation of harmonics of the modulation frequency at subharmonics resonances of the system. The experimental results are in very good agreement with the numerical results obtained from the most simple dynamical model for such type of lasers.

期刊介绍： Physica D (Nonlinear Phenomena) publishes research and review articles reporting on experimental and theoretical works, techniques and ideas that advance the understanding of nonlinear phenomena. Topics encompass wave motion in physical, chemical and biological systems; physical or biological phenomena governed by nonlinear field equations, including hydrodynamics and turbulence; pattern formation and cooperative phenomena; instability, bifurcations, chaos, and space-time disorder; integrable/Hamiltonian systems; asymptotic analysis and, more generally, mathematical methods for nonlinear systems.
