论文摘要
我们分析了腔体增强的第二谐波一代中局部结构的形成。我们专注于相匹配的极限，并认为基本和产生的波具有相反的群体速度分散体的迹象。我们表明，由于连接系统的两个稳定均匀状态的域墙的锁定，这些状态形成，并经历了崩溃的蛇。我们研究时间散步对这些局部状态的稳定性和动态的影响。
We analyze the formation of localized structures in cavity-enhanced second-harmonic generation. We focus on the phase-matched limit, and consider that fundamental and generated waves have opposite sign of group velocity dispersion. We show that these states form due to the locking of domain walls connecting two stable homogeneous states of the system, and undergo collapsed snaking. We study the impact of temporal walk-off on the stability and dynamics of these localized states.
