Research focuses on the development and application of ultrashort wavelength lasers. Physics concepts such as optics, plasma physics, atomic physics, and spectroscopy are utilized to implement these new types of laser devices. Currently, students under Dr. Rocca are working to develop new sources of light, while making those sources practical. The NSF-supported Engineering Research Center for Extreme Ultraviolet Science and Technology, a multi-institutional center, is working toward developing lasers that are more compact and cost efficient, to be used in the same widespread manner as most visible and ultraviolet lasers today.
