MW-level 7ps high-power MOPA system with ytterbium-doped spun tapered double-clad fiber
This paper presents the development and experimental demonstration of all-fiber Master Oscillator Power Amplifier (MOPA) systems capable of delivering high-average-power and high-peak-power picosecond...
PublikationenZnO-doped preform preparation approaches towards radioluminescent optical fibers
Zinc oxide (ZnO)-doped silica exhibits radioluminescent properties, attributed to the presence of the crystalline zinc silicate willemite (Zn2SiO4), making it a promising material for fiber-based radiation...
PublikationenIndex-matching of individual glass preforms: high-volume synthesis and high-precision refractive index measurements
We will present an overview on recent advances in high-volume synthesis starting from the powder-based concept of REPUSIL to create high-purity silica preform materials on demand. Emphasis is placed on...
PublikationenSoft X-ray imaging with coherence tomography in the water window spectral range using highharmonic generation
High-harmonic generation (HHG) is used as a source for various imaging applications in the extreme ultraviolet spectral range. It offers spatially coherent radiation and unique elemental contrast with...
PublikationenSulfate-Directed Silver Dendrites with Enhanced Stability for Ultrasensitive SERS-Based Therapeutic Drug Monitoring
Silver-based surface-enhanced Raman spectroscopy (SERS) substrates offer exceptional signal enhancement but suffer from poor long-term stability due to oxidative degradation, limiting their utility for...
PublikationenPulse Compression in Ho:ZBLAN Photonic Crystal Fiber Using a NOLM Configuration for Ultrashort Mid-IR Generation
We propose and design a holmium-doped ZBLAN (Ho:ZBLAN) tapered photonic crystal fiber (TPCF) for generating ultrashort mid-infrared (mid-IR) pulses at 2.86 μm, utilizing a nonlinear optical loop mirror...
PublikationenFemtosecond laser micromachining triple-modality optical fiber sensor with multiband optical decoupling for simultaneous dual-biomarkers and temperature monitoring
To address the insufficient information from single-parameter biological detection, this study proposes a multi-parameter optical biosensing scheme based on femtosecond laser micromachining (FLM), enabling...
PublikationenEngineering Aptameric Responsive Photonic Biosensor Based on Cholesteric Liquid Crystal Network for the Detection of Anatoxin
The rapid and reliable detection of cyanobacterial toxins remains a pressing challenge for environmental monitoring. In this work, we present a novel portable optical biosensor fabricated entirely from...
PublikationenRaman signatures of single point defects in hexagonal boron nitride quantum emitters
Point defects in solid-state quantum systems are vital for enabling single-photon emission at specific wavelengths, making their precise identification essential for advancing applications in quantum technologies....
PublikationenGeneration of an Induced Pluripotent Stem Cell-Derived Alveolar Type II In Vitro Model to Study Influenza A Virus Infection and Drug Treatments
Influenza viruses (IVs) represent a significant global health issue, capable of causing seasonal epidemics and occasional pandemics with substantial morbidity and mortality. The emergence of viral resistance...
