" Our research projects are focused on the Interaction of Femtosecond Laser Pulses with Matter. "
Our research in collaboration with students, research associates and other researchers in Waterloo in Canada and beyond, focuses on understanding the way that intense laser radiation in extremely short femtosecond pulses* interacts with and modifies matter.
What is Femtosecond?
* one femtosecond is one thousand million millionth of a second or 10 -15s.
In addition we want to exploit it in order to image molecular processes on the fastest timescales, using the technique of Coulomb imaging. We can also use it to modify matter in order to generate nano particles and fabricate nano scale structures, as well as to explore new therapeutic possibilities.

The key to understanding how these laser pulses have such a dramatic effect on matter is to consider the massive electric field which they create for a short time. This field is bigger than the one which binds electrons to an atom and so the interaction can rip matter apart. We are interested in understanding how this process happens, and how we can harness it to image matter and create matter with new useful properties.
