21. Development and application of laser diagnostics - from laboratory devices towards practical combustion engines
Abstract : For many decades, research work on combustion has been focused on improving combustion efficiency and reducing harmful emissions. Laser diagnostics is one of the best ways to investigate the combustion process and emission formation as it is non-intrusive and it has high spatiotemporal resolution. READ MORE

22. Collisional effects and attosecond diagnostics in laser-generated plasmas
Abstract : When matter is radiated by laser light of extreme intensity, it is rapidly ionized, thereby forming a plasma. Such laser-generated plasmas can be used as sources of energetic particles and radiation, or to study astrophysically relevant phenomena in the laboratory and the behavior of matter under extreme conditions.

23. High Repetition Rate Laser Diagnostics for Combustion Applications
Abstract : High repetition rate laser diagnostics has proven to be a useful tool for studying combustion phenomena. Laser techniques are, in general, relatively non-intrusive and have the potential to measure specific species at very low concentrations and with extremely high temporal resolution. READ MORE

25. Development and Application of Non-linear Mid-infrared Laser Spectroscopy for Combustion Diagnostics
Abstract : The work reported in this thesis involved the development and application of two novel infrared non-linear laser techniques, namely mid-infrared polarization spectroscopy (IRPS) and mid-infrared degenerate four-wave mixing (IR-DFWM) to combustion diagnostics. These two techniques meet the needs of species concentration detection in combustion environments, especially for those species lacking accessible electronic (one-photon) transitions in the ultraviolet (UV) or visible spectral region.
