论文摘要
我们基于非线性空间模式耦合，证明了MID-IR CR：ZnS波导激光器中时空模式锁定的可行性。该实验通过激发模式殴打的激发显示了有效的功率缩放，从而引起明显的Q开关，这可能会导致非线性模式耦合。我们建议在Cr：Zns中与多模型波导结合的非线性特别高导致泵束诱导的软孔。后者在非线性多模型波导中提供了有效的空间模式控制，从而为时空耗散孤子或轻弹形成开辟了道路。因此，为未来分布的Kerr-Lens模式锁定的基础在能量量表的固态波导（或未实现的纤维）激光器中。
We demonstrate feasibility of spatiotemporal mode-locking in a mid-IR Cr:ZnS waveguide laser based on the nonlinear spatial mode coupling. The experiment shows efficient power scaling with the excitation of intra-mode beatings, causing a pronounced Q-switching which could cause a nonlinear mode-coupling. We suggest that a particularly high nonlinearity in Cr:ZnS combined with multimode waveguide leads to a soft aperture induced by a pump beam. The latter provides an effective spatial mode control in a nonlinear multimode waveguide and, thereby, opening the way to the birth of a spatiotemporal dissipative soliton, or light bullet, formation. Thus, forming the basis for the future distributed Kerr-Lens Mode Locking in the energy-scalable solid-state waveguide (or yet unrealized fiber) laser.
