Microcirculation describes the circulation of blood in the smallest vessels. The publication of Moritz Späth deals with the “Determination of the diameter of simulated human capillaries using shifted position‐diffuse reflectance imaging”. Using Monte-Carlo simulations, he showed that this non-invasi...

Photovoltaic energy generation will play a major role in the future of producing electric energy. “Outdoor photoluminescence of large area photovoltaic modules”, investigated by Bernd Doll, can act as an on-site tool for fast and cost-effective characterization of solar cells. For investigation o...

Yakun He successfully worked on “Unraveling the Charge-Carrier Dynamics from the Femtosecond to the Microsecond Time Scale in Double-Cable Polymer-Based Single-Component Organic Solar Cells”. She investigated the charge carrier dynamics of a representative polymer across seven orders of magnitude in...

Thermal lensing is an unwanted effect in optics used for high-power laser imaging. The high light intensity causes a heat up of the lenses which induces a focus shift. To tackle this issue, Phillip Rall recently presented a “Simulation and compensation of thermal lensing in high-power optical system...

The recent publication of Lisa Ackermann deals with “Uniform and efficient beam shaping for high-energy lasers”. By setting two spatial light modulators in a proper arrangement, she realized a setup that enables tailored light fields even for high-energy pulsed lasers. Thus, she was able to create a...
