Real-time observation of the optical Sagnac effect in ultrafast bidirectional fibre lasers
The optical Sagnac effect sets fundamentals of the operating principle for ring laser and fiber optic gyroscopes, which are preferred instruments for inertial guidance systems, seismology, and geodesy....
PublikationenDirect identification of chlamydiae from clinical samples using a DNA microarray assay-A validation study
While DNA microarrays have become a widely accepted tool for mRNA expression monitoring, their use in rapid diagnosis of bacterial and viral pathogens is only emerging. So far, insufficient sensitivity...
PublikationenStructures for surface enhanced non-plasmonic or hybrid spectroscopy
Absorption, scattering, and fluorescence are processes that increase with electric field intensity. The most prominent way to enhance electric field intensity is to use localized or propagating surface...
PublikationenSimple differentiation of Salmonella Typhi, Paratyphi, and Choleraesuis from Salmonella spp. using the eazyplex® TyphiTyper LAMP assay
Introduction. Identification of typhoidal Salmonella (TS) serovars and their discrimination from non-typhoidal Salmonella (NTS) is conventionally performed by seroagglutination. This method is labour-intensive,...
PublikationenOptical properties of ytterbium/aluminium doped silica glasses
Several series of preform and fiber samples of Yb2O3-Al2O3-SiO2 glass with finelygraded composition steps were prepared by MCVD and solution doping under well-defined conditions. Their optical properties,...
PublikationenGuidelines for the use of flow cytometry and cell sorting in immunological studies (second edition)
These guidelines are a consensus work of a considerable number of members of the immunology and flow cytometry community. They provide the theory and key practical aspects of flow cytometry enabling immunologists...
PublikationenDisturbing-Free Determination of Yeast Concentration in DIWater and in Glucose Using Impedance Biochips
Deionized water and glucose without yeast and with yeast (Saccharomyces cerevisiae) of optical density OD600 that ranges from 4 to 16 has been put in the ring electrode region of six different types of...
PublikationenHigher-Order Soliton Generation in Hybrid Mode-Locked Thulium-Doped Fiber Ring Laser
A thulium-doped all-fiber laser passively modelocked by the co-action of nonlinear polarization evolution and single-walled carbon nanotubes operating at 1860–1980 nm wavelength band is demonstrated....
PublikationenHigh Power Q-Switched Thulium Doped Fibre Laser using Carbon Nanotube Polymer Composite Saturable Absorber
We have proposed and demonstrated a Q-switched Thulium doped fibre laser (TDFL) with a ‘Yin-Yang’ all-fibre cavity scheme based on a combination of nonlinear optical loop mirror (NOLM) and nonlinear...
PublikationenSESAM and SWCNT Mode-Locked All-Fiber Thulium-Doped Lasers Based on the Nonlinear Amplifying Loop Mirror
We report on thulium-doped all-fiber lasers based on the nonlinear amplifying loop mirror and mode-locked with a semiconductor saturable absorber (SESAM) or single-walled carbon nanotubes (SWCNTs). An...
