Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies
FEBS Open Bio, EarlyView.We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Cascaded Cladding Light Extracting Strippers for High Power Fiber Lasers and Amplifiers
IEEE Photonics Journal, 2014 We demonstrate efficient cladding light extracting through cascaded strippers for high-power fiber lasers and amplifiers. A selected part of the fiber is divided into five segments, and the fluoroacrylate jackets of three interval segments are gradually ...

Modeling of Graded-Index Raman Fiber Amplifiers with Pump Depletion
PhotonicsGraded-index (GRIN) fibers are often used for making high-power Raman amplifiers. We employ numerical and semi-analytical techniques to model such amplifiers and include not only the signal’s amplification and pump’s depletion but also various nonlinear ...

Mode instability thresholds for Tm-doped fiber amplifiers pumped at 790 nm. [PDF]
Optics Express, 2015 We use a detailed numerical model of stimulated thermal Rayleigh scattering to compute mode instability thresholds in Tm(3+)-doped fiber amplifiers. The fiber amplifies 2040 nm light using a 790 nm pump. The cross-relaxation process is strong, permitting

Thermal resilience of polymer-coated double-clad fiber
, 2009 Following the advance of ytterbium-doped fiber laser to kW-level cw-output power, there is a particular interest in using shorter fiber length with large cores since they mitigate detrimental nonlinear effect such as stimulated Raman and Brillouin ...

Advanced Engineering Materials, EarlyView.Mg–Zn composites with a thickness of 0.21 mm were fabricated using roll bonding of a kirigami‐patterned Mg alloy inlay within a Zn matrix. Thermal activation following this process led to the formation of tailored intermetallic structures, which provided the composite with enhanced flexural strength.

Spatial Beam Self-Cleaning in Tapered Yb-Doped GRIN Multimode Fiber With Decelerating Nonlinearity
IEEE Photonics Journal, 2020 We experimentally demonstrate spatial beam self-cleaning in an Yb-doped graded-index multimode fiber taper, both in passive and active configurations. The input laser beam at 1064 nm was injected for propagation from the small to the large core ...
