标题： Time-Stretch Probing of Ultrafast Soliton Molecule Dynamics

摘要： 孤子分子是通过非线性介质介导的光脉冲之间的吸引和排斥相互作用的表现。 然而，由于这一过程的瞬态性质，孤子分子的形成和破裂难以观察。 使用时间拉伸技术，我们能够跟踪飞秒光纤激光器中束缚态形成的实时演化，并揭示通向稳定束缚态的不同演化路径。 在此过渡期间，观察到一个非稳态的Q开关锁模 regime，其中包含各种瞬态孤子。 我们还观察到包括孤子分子振动、碰撞和衰减在内的额外动力学行为。 我们的发现揭示了光学非线性系统中多样化的孤子动力学，并为进一步的理论研究提供了有价值的数据。 显示英文摘要

摘要： Soliton molecules are the manifestation of attractive and repulsive interaction between optical pulses mediated by a nonlinear medium. However, the formation and breakup of soliton molecules are difficult to observe due to the transient nature of the process. Using the time stretch technique, we have been able to track the real-time evolution of the bound state formation in a femtosecond fiber laser and unveil different evolution paths towards a stable bound state. A non-stationary Q-switched mode-locking regime consisting of various transient solitons is observed in this transition period. We also observe additional dynamics including soliton molecule vibrations, collision and decay. Our findings uncover a diverse set of soliton dynamics in an optical nonlinear system and provide valuable data for further theoretical studies.
