16. Correlation spectrosopy of single emitters : fundamental studies and applications related to quantum optics and life science
Abstract : Correlation analysis and correlation spectroscopy has eversince the first developments, to characterise light emittingprocesses and biomolecular dynamics, continued to extend itspractical applicability. Today, correlation spectroscopy can beused in life science to study dynamical processes even at thesingle molecule level. READ MORE

17. Laser Scanning Multiphoton Microscopy – Focusing on Fluorescence Correlation Spectroscopy and Fluorescence Lifetime Imaging for Biomedical Applications
Abstract : Laser scanning multiphoton microscopy (MPM) is considered as a non-invasive technology for three-dimensional imaging of complex biological tissues. The quantitative potential of the MPM is not investigated as much as qualitative imaging. READ MORE

18. Femtosecond Dynamics and Photochemistry in Solution
Abstract : The reaction dynamics of several polyatomic systems have been investigated in solution by femtosecond spectroscopy. Tetranitromethane-naphtalene complexes excited in the charge-transfer band at 400 nm undergo dissociative electron transfer, resulting in three primary products: [naphthalene].+, NO2 and C(NO2)3-.

19. Methods of laser spectroscopy in the study of Pb₂, CaCl and CaH
Abstract : Some methods of laser spectroscopy in the study of small molecules are discussed. A special emphasis is given on to how quantum number assignments can be made and rotational analyses of very dense structures can be carried out after exciting the molecules with monochromatic radiation.

20. Photon Upconversion in Heavily Doped Semiconductors
Abstract : In this thesis the luminescence properties of highly doped semiconductors are studied with focus on degenerately n-doped InP. It is demonstrated how photoluminescence measurements on degenerately doped semiconductors allow an estimation of the doping concentration without need for electrical contacts. READ MORE
