Having access to fluorescence lifetime, researchers can reveal in-depth details about the microenvironment as well as the physico-chemical state of the molecule under investigation. However, the high number of influencing factors might be an explanat

Bioinspired 3D microfluidic systems that combine vascularization with extracellular matrix architectures of organotypic geometry, composition and biophysical traits can help advance our understanding of microorgan physiology. Here, two-photon stereol

We present a two-color two-photon stimulated emission depletion microscopy technique (2C2P-STED) that correlates a confocal image with a super-resolved image employing the inherent self-referencing mechanism of nonlinear excitation. The novel approac

We present numerical simulations and experiments employing two-photon excited fluorescence in a sum-frequency mixing scheme which could be used for colocalization experiments in biophysics. By means of numerical calculations using the Debye approxima

In this Letter, we present an all-fiber, easy-to-use, wavelength-tunable, ultrafast laser, based on soliton self-frequency shifting in an Er-doped polarization-maintaining very large mode area fiber. The system is tunable over 370 nm, starting at 162

In this manuscript, we present a detailed investigation of the impact of dispersion on the spectral resolution achievable by the application of spectral focusing in coherent Raman imaging. Our results reveal the detrimental effect of third order disp

Femtosecond lasers had an unpredictable success in optical sciences ever since they were introduced. Today physicists are still pushing the limits of ultrafast lasers, e.g. the pulse duration down to a single optical cycle and the peak power up to te

Better understanding of the fundamental mechanisms behind metabolic diseases requires methods to monitor lipid stores on single-cell level in vivo . We have used Caenorhabditis elegans as a model organism to demonstrate the limitations of fluorescenc

In this work, we show how broad-bandwidth femtosecond pulses can be used to achieve high spectral resolution in nonlinear spectroscopy and microscopy. Our approach is based on chirping the excitation pulses in order to focus their entire bandwidth in
