A study on the amplification of active-mirror Yb:YAG lasers
Kuwait Journal of Science, 2018 Thermal effects and amplified spontaneous emission (ASE) are two main factors in the design of high-power and high-energy laser amplifiers. The temperature distribution and the lateral ASE of the face-pumped active-mirror Yb:YAG amplifiers are analyzed ...

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 ...

Lifetime quenching in Yb doped fibres
, 1997 We have discovered that in ytterbium-doped silica fibres the excited state lifetime of a fraction of the Yb ions can be quenched to a very small value, leading to a strong unbleachable loss.

Advanced Functional Materials, EarlyView.An oral nanoplatform, MOP@T@D, which can maintain glucose homeostasis and restore islet β cells in diabetic rats is developed. It achieves efficient intestinal absorption and liver‐targeted delivery. The nanoparticle disintegrates only in response to hyperglycemia to release insulin on demand and provides antioxidant protection through selenoprotein ...
