The Ultrafast Physics Group develops and employs novel ultrafast (sub-nanosecond) spectroscopic techniques to study the fundamental physical properties of matter and also fabricates the custom ultra-short pulse laser radiation sources required for such investigations.

Pacific Northwest National Laboratory
The Applied Laser group collaborates with the Pacific Northwest National Laboratory to develop an ultrafast electron microscope (UEM) – an instrument that seeks to combine the high spatial (sub-nanometer) resolution of electron microscopy with the high temporal resolution afforded by today’s ultrafast laser systems. The successful development of a single-shot imaging UEM will offer unprecedented space-time resolution for investigations into, for example, structural changes in biology, condensed matter phase transformations, and the structural dynamics of individual nano-particles.
Time and Angle-Resolved Photoemission Spectroscopy
A future project, in collaboration with Professor Campuzano, will add time resolution to angle-resolved photoemission spectroscopy (ARPES) through the development of a picosecond-laser-driven 15-20eV radiation source. This spectroscopic technique will allow the band structure of initially unoccupied states to be determined and the excited state electron dynamics to be studied.
