1. 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

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.

4. Short Attosecond Pulse Trains at High Repetition Rates for Novel Pump-Probe and Coincidence Studies
Abstract : This work aims at studying photoionization dynamics from atoms and surfaces at attose time scales. The work was based on development and applications of a high repetition rate High-order Harmonic Generation (HHG) light source that utilizes Optical Parametric Amplification (OPA) laser technology.

5. Second-generation High-Order Harmonic Sources — From CPA to OPCPA
Abstract : This thesis presents two sources of extreme ultraviolet (XUV) radiation based on high-order harmonic generation (HHG) in gases. The sources were developed for experiments requiring high-flux harmonic beams or HHG pulses at high-repetition rate. These were used experimentally to image nano-scale objects. READ MORE
