The impact of the different reconstruction parameters in super-resolution structured illumination microscopy (SIM) on image artifacts is carefully analyzed. These parameters comprise the Wiener filter parameter, an apodization function, zero-frequenc

Selected semiconductor nanostructures provide extremely localized coherent light sources. Here an ensemble of CdS nanostructures was excited by UV/vis femtosecond laser pulses and their ultrafast luminescence characteristics were investigated as func

Nonlinear pulse propagation inside highly nonlinear media requires accurate knowledge on the temporal response function of the materials used particular in the case of liquids. Here we study the impact of deuteration on the ultrafast dynamics of tolu

We propose a chiral imaging modality based on optical chirality engineering, fluorescence-detected circular dichroism and structured illumination microscopy. In this method, the optical chirality of the illumination is structured and the circular dic

Mirror reflectance values above \( R > 0.999 \) can be accurately determined by measuring the life time of photons coupled into a cavity consisting of at least two of these mirrors (Cavity ring-down, CRD). This technique is superior compared to other

Femtosecond (fs) laser pulses at variable delay times allowed us to track the fast non-radiative transitions between the manifold of highly excited \(\mathrm{M}_{\mathrm{Na}}^{**}\) states to the lower lying fluorescent \(\mathrm{M}_{\mathrm{Na}}^{*}
