Active Stabilization of Laser Diode Injection Using a Polarization-Spectroscopy Technique

Autor: Milanovic, Luka, Ferrero, Greg, Oswald, Robin, Kinder, Thomas, Schmidt, Julian, Hempel, Cornelius

Laser diode injection-locking is a commonly used method to amplify laser light, while preserving its spectral properties. Fluctuations in the environmental conditions can cause injection-locking to fail, especially when operating with low seed powers

The Potential of Geminate Pairs in Lead Halide Perovskite revealed via Time-resolved Photoluminescence

Autor: Hempel, Hannes, Stolterfoht, Martin, Karalis, Orestis, Unold, Thomas

Photoluminescence (PL) under continuous illumination is commonly employed to assess voltage losses in solar energy conversion materials. However, the early temporal evolution of these losses remains poorly understood. Therefore, we extend the methodo
