Research on Passive Q-switching Large-Energy near Infrared and Red Fiber Lasers with Nano-Materials [PDF]
, 2016 脉冲光纤激光器可广泛应用于工业、医疗和科研等领域，锁模和调Q为光纤激光器中实现脉冲操作的常见技术。锁模技术对光纤激光器腔体的增益、损耗和色散以及可饱和吸收体（SA）的性能都有一定的要求，对比之下，调Q技术的要求较低，往往更易实现。近年来，基于石墨烯等新型纳米材料的调Q技术受到了极大的关注。相比于传统的半导体可饱和吸收镜（SESAM）和碳纳米管，新型纳米材料具有诸如高度光纤兼容性、大调制深度、超快恢复时间和独特的超宽带可饱和吸收特性等优点。因此，新型纳米材料SAs已被广泛应用于各种光纤激光器中实现调Q操作。

Substrate Stress Relaxation Regulates Cell‐Mediated Assembly of Extracellular Matrix
Advanced Functional Materials, EarlyView.Silicone‐based viscoelastic substrates with tunable stress relaxation reveal how matrix mechanics regulates cellular mechanosensing and cell‐mediated matrix remodelling in the stiff regime. High stress relaxation promotes assembly of fibronectin fibril‐like structures, increased nuclear localization of YAP and formation of β1 integrin‐enriched ...
