"By the light flash being there for only a short time, you can freeze the motion of the electrons and get a very sharp picture of the electron at the time the light illuminates it," Kling said. "By putting lots of these pictures together, we obtain a movie of electron motion across the nanostructure."
Kling has spent a research leave at the Max Planck Institute of Quantum Optics in Garching, Germany, where he performed preliminary research on this project. He helped to record correlated electron motion with light waves and studied how to use short laser pulses to control electron motion -- all fundamental to what Kling will apply to nanosystems in the Macdonald Laboratory.
A new laser, a new laboratory space
For his research, Kling will use ultrafast laser sources from the Macdonald Laboratory and he will work in a new laboratory space being built at the lab. The space will be completed this summer.
The new space will include a new $1.3 million laser system funded by the Department of Energy. The university is providing more than $500,000 to fund the laboratory space.
"The new lab space is a state-of-the-art ultrafast laser lab," said Itzik Ben-Itzhak, university distinguished professor of physics and director of the Macdonald Laboratory. "It accommodates a high repetition rate, intense laser system that will serve a multitude of experiments mainly focused on attosecond physics. These experiments and the laser system require a high level of environmental control, which the new lab provides."
In addition to Kling, other researchers with the Macdonald Laboratory group will use the space to study the interaction of ultrashort laser pulses with matter.
"This lab and laser system will put the Macdonald Laboratory group among the leading laboratories in the world of attosecond science research," Ben-Itzhak said.
