1. Laser Spectroscopic Techniques for Combustion Diagnostics Directed Towards Industrial Applications
Abstract : In the work presented in the thesis, different laser spectroscopic techniques were utilized for measurement of species concentrations, as well as for surface thermometry. Experiments were conducted in various combustion environments, ranging from laboratory burners to truck-sized internal combustion (IC) engines, gas turbine combustors and a full-size aircraft turbofan engine.

2. Laser Diagnostic Techniques with Ultra-High Repetition Rate for Studies in Combustion Environments
Abstract : When conducting laser based diagnostics in combustion environments it is often desirable to obtain temporally resolved information. This can be due to several factors such as combustion taking place in a turbulent flow field, flame propagation from a spark plug in an initially quiescent combustible mixture, or rapid, multi-point fuel consumption in a homogeneous charge as a result of compression ignition in an engine cycle.

5. Development of a 2D Temperature Measurement Technique for Combustion Diagnostics using 2-Line Atomic Fluorescence
Abstract : The present thesis is concerned with the development and application of a novel planar laser-induced fluorescence (PLIF) technique for temperature measurements in a variety of combusting flows. Accurate measurement of temperature is an essential task in combustion diagnostics, since temperature is one of the most fundamental quantities for the characterization of combustion processes.
