Sensitive und absolute Absorptionsmessung mittels laserinduzierter Teststrahlablenkung (LID)

Hohe Sensitivität gepaart mit einfacher absoluter Kalibrierung, das am IPHT Jena entwickelte LID-Absorptionsmessverfahren vereint beides. Das neue „LID-Sandwich-Konzept“ erlaubt darüber hinaus die...

Bessel beam coherent anti-Stokes Raman scattering microscopy

We report about laser scanning coherent anti-Stokes Raman scattering (CARS) microscopy using a Bessel beam to enhance the lateral resolution. This study covers a numerical investigation that predicts an...

Dye-sensitized PS-b-P2VP-templated nickel oxide films for photoelectrochemical applications

Moving from homogeneous water-splitting photocatalytic systems to photoelectrochemical devices requires the preparation and evaluation of novel p-type transparent conductive photoelectrode substrates....

SiO2-Al2O3-La2O3 Glass – a Superior Medium for Optical Kerr Gating at Moderate Pump Intensity

Novel SiO2-Al2O3-La2O3 glass shows a switching efficiency   70 % in  = 140 fs for dual wavelengths optical Kerr gating at 1 TW/cm2 and is compared to other Kerr materials with larger n2.

Temporal walk-off affecting optical Kerr gating in the sub-ps time range

During the past decades, optical Kerr gating (OKG) evolved to one of the most important optical switching techniques for broadband analysis of ultrafast optical processes [1]. For maximum OKG efficiency...

Temporal walk-off affecting optical Kerr gating in the sub-ps time range

The temporal walk-off between pump and signal pulses in broadband optical Kerr gating was analyzed and found to be critical addressing spectral and temporal characterization in the sub-ps regime.

Quantitative SERS studies by combining LOC-SERS with the standard addition method

Here, we report on a proof-of-concept study highlighting a new approach for quantitative surface enhanced Raman spectroscopy (SERS) measurements. This has been achieved by implementing the standard addition...

Bio-nano composite for remote melting

Rapid, culture-independent, optical diagnostics of centrifugally captured bacteria from urine samples

This work presents a polymeric centrifugal microfluidic platform for the rapid and sensitive identification of bacteria directly from urine, thus eliminating timeconsuming cultivation steps. This “Lab-on-a-Disc”...

Soliton scattering as a measurement tool for weak signals

We have considered relativistic soliton dynamics governed by the sine-Gordon equation and affected by short spatial inhomogeneities of the driving force and thermal noise. Developed analytical and numerical...
