Efficient single frequency fibre lasers using novel photosensitive Er/Yb optical fibres
, 1997 Boron- and germanium-doped highly photosensitive cladding is used in a novel design to achieve photosensitive Er/Yb-doped fibers, permitting short, strong gratings (length ~1cm, reflectivity >99%) to be written without hydrogenation.

Physics Procedia, 2012 AbstractAn innovative laser cladding technology based on laser scanning is presented. The variable scan width allows adjusting the dimensions of the weld seams on-line in a broad range for a flexible adaption of specific requirements concerning the part's geometry. Additionally, an enhancement of the deposition rate is achieved.

Advanced Science, EarlyView.Microproteins are hidden treasures encoded by the “dark proteome” but remain largely underexplored due to the lack of highly efficient tools. We developed a molecularly imprinted polymers (MIPs)‐based toolbox (CLAIMID) to achieve accelerated and ultrasensitive microproteins validation at multiple biological scales (single living cells, cell populations,

Advanced Science, EarlyView.ABSTRACT The combination of metasurfaces with chalcogenide phase‐change materials is a highly promising route toward the development of multifunctional and reconfigurable nanophotonic devices. However, their transition into real‐world devices is hindered by several technological challenges. This includes, amongst others, the lack of large area photonic

Depressed clad hollow optical fiber with fundamental LP01 mode cut-off
, 2006 We propose a depressed clad hollow optical fiber with fundamental (LP01) mode cut-off suitable for high power short-wavelength, especially three-level, fiber laser operation by introducing highly wavelength dependent losses at longer wavelengths. The cut-
