N1 - The design of this system was closely based on one originally provided by Professor David Rothamer. This research was sponsored by the DEVCOM Army Research Laboratory and was accomplished under Cooperative Agreement Numbers W911NF-20-2-0220, W911NF-19-2-0239, and W911NF-18-2-0240(ORAU Student Fellowship).

N2 - The need for an ultra-high-speed pulsed laser system to produce noninvasive measurements has led to leaps in laser generation strategies, with the burst-mode laser at the top of this list. Through the sacrifice of continuous operation, the burst mode system is capable of providing significant pulse energies for many applications at kHz rates. This report explores the concepts and architecture of a system that has the potential to be a source that can operate at high speeds for extended durations and be both reasonably affordable and compact. Additionally, a demonstration measurement of formaldehyde PLIF was performed as a first look into the system’s potential for use on reacting flows. Future demonstrations and modifications to the system are also detailed.
