论文摘要
在本文中，我们分析了耦合到可远距离饱和吸收剂的激光输出中，光弹的结合状态（BS）的动力学和形成机理。首先，我们通过管理横向轮廓的动力学的简化方程来近似整个三维的HAU主方程组。这种有效的理论使我们能够进行详细的多参数分叉研究，并确定BSS不稳定性的不同机制。此外，我们的分析揭示了稳定区域作为线宽增强因子和场扩散的函数的非直觉依赖性。通过直接对完整系统的数值模拟确认了我们的结果。
In this paper, we analyze the dynamics and formation mechanisms of bound states (BSs) of light bullets in the output of a laser coupled to a distant saturable absorber. First we approximate the full three-dimensional set of Haus master equations by a reduced equation governing the dynamics of the transverse profile. This effective theory allows us to perform a detailed multiparameter bifurcation study and to identify the different mechanisms of instability of BSs. In addition, our analysis reveals a non-intuitive dependence of the stability region as a function of the linewidth enhancement factors and the field diffusion. Our results are confirmed by direct numerical simulations of the full system.
