Research Overview

The ability to manipulate and alter matter with intense light fields on very short timescales has the potential to have a transformative effect on a range of scientific and technological endeavors in the coming decades. With extremely high peak powers delivered in exceedingly brief periods of time, ultrafast pulses of light provide the perfect tools to pursue these ideas. They allow the exploration of nonlinear phenomena across broad regions of the electromagnetic spectrum, as well as the measurements of fast electron dynamics in matter. Starting with the development of a strong and unique suite of ultrafast capabilities from the ground up at OIST, and sharing OIST’s vision to pursue creative, interdisciplinary research, we have pursued three broad areas of study:
