Physics Colloquium: High-Harmonic and Attosecond-Pulse Generation, Measurement, and Application
Tuesday, January 16, 2024 from 3:30 pm to 4:30 pm
- In-person event
- Mackenzie, Carleton University
- 1125 Colonel By Drive, Ottawa, ON, K1S 5B6
In this Carleton University Physics Colloquium, special guest speaker Dr. Paul Corkum will discuss the contribution of each winner of the 2023 Nobel Prize in Attosecond Science and as he does, he will introduce key attosecond ideas. He will also discuss why the Nobel Committee might have chosen “attosecond science” for the 2023 Prize and where could it lead.
Dr. Corkum will then turn to three applications from his lab (1) “imaging an orbital”, (2) measuring the “properties of a two-band semiconductors” and (3) measuring the “attosecond delay of a photoelectron near the Cooper minimum in Argon”.
The lecture will be accessible to undergraduate students of Physics.
Attend in person or on Zoom! (Meeting ID: 917 0893 6858/Passcode: physics)
ABOUT THE PRESENTER
Dr. Paul Corkum, Joint Attosecond Science Laboratory, National Research Council Chair in Attosecond Photonics, University of Ottawa
Dr. Corkum uses quick bursts of infrared light on atoms to create super-fast X-ray flashes. This allows for incredibly fast measurements in science. By manipulating ionized electrons with laser light, unique X-ray flashes are generated—the fastest human-made measurements possible.
These interacting electrons can capture atomic positions or create an “orbital selfie” of the original electron.
Dr. Corkum’s recent work focuses on innovative measurement methods in attosecond science. His team has measured electron behavior using a new method. Looking ahead, Dr. Corkum aims to measure the ultimate time response of electronic matter.
