    An established method for precise determination of optical absorption is the so called laser calorimetry. According to ISO 115511 laser calorimetry is preferred to other photothermal test methods, because of its capability ...

    The sensitivity of laser interferometers can be pushed into regimes that enable the direct observation of the quantum behaviour of mechanical oscillators. In the past, membranes with subwavelength thickness (thin films) ...
  • Wittel, H.; Affeldt, C.; Bisht, A.; Doravari, S.; Grote, H.; Lough, J.; Lück, H.; Schreiber, E.; Strain, K.A.; Danzmann, Karsten (Washington, DC : Optical Society of America, 2018)
    Large scale laser interferometric gravitational wave detectors (GWDs), such as GEO 600 require high quality optics to reach their design sensitivity. The inevitable surface imperfections, inhomogeneities, and light-absorption ...
  • Taffa, Dereje H.; Dillert, Ralf; Ulpe, Anna C.; Bauerfeind, Katharina C.L.; Bredow, Thomas; Bahnemann, Detlef W.; Wark, Michael (Bellingham, WA : S P I E - International Society for Optical Engineering, 2017)
    Solar-assisted water splitting using photoelectrochemical cells (PECs) is one of the promising pathways for the production of hydrogen for renewable energy storage. The nature of the semiconductor material is the primary ...

    Femtosecond-pulse-induced (Epump = 2:5 eV) picosecond infrared absorption is studied in the spectral region between 0.30 eV and 1.05 eV in LiNbO3:Mg. We find a noninstantaneous mid-infrared absorption peak in the time ...
