论文摘要
孤子分子（SMS）是非线性光学系统中重要的模式。在模式锁定的纤维激光器中，实验生产具有所需时间分离的SMS是一个挑战。在这里，我们提出并实现了在激光设置中利用SM动力学的实验场景。特别是，我们在由二阶组速度分散和分散损失控制的模式锁定激光器中量身定制SMS：分散的实际部分保持分散和非线性之间的平衡，而色散损失决定增益和损失的平衡。实验结果表明，分散损失使在系统中SMS的结合对选择时间分离（TS）的所需值成为可能。 SM的中心波长和相应滞后的可调性也被解决。所展示的制度使我们能够创建具有TS和中心波长预选值的多个SMS，这表明了我们设置对设计光学数据处理方案设计的潜力。
Soliton molecules (SMs) are fundamentally important modes in nonlinear optical systems. It is a challenge to experimentally produce SMs with a required temporal separation in mode-locked fiber lasers. Here, we propose and realize an experimental scenario for harnessing SM dynamics in a laser setup. In particular, we tailor SMs in a mode-locked laser controlled by second-order group-velocity dispersion and dispersion losses: the real part of dispersion maintains the balance between the dispersion and nonlinearity, while the dispersion loss determines the balance of gain and losses. The experimental results demonstrate that the dispersion loss makes it possible to select desired values of the temporal separation (TS) in bound pairs of SMs in the system. Tunability of the SM's central wavelength and the corresponding hysteresis are addressed too. The demonstrated regime allows us to create multiple SMs with preselected values of the TS and central wavelength, which shows the potential of our setup for the design of optical data-processing schemes.
