Ultrafast terahertz nanoscopy laboratory

Imaging the femtosecond dynamics of electrons in atoms, molecules, and solids

Open post-doc position

We are currently hiring a post-doctoral researcher for a joint project with the group of Prof. Chong-Yu Ruan. Further information on the position and how to apply can be found in the links below.


After intensive building and testing, in March 2019 our terahertz scanning tunneling microscope (THz-STM) measures its first THz-pulse-driven tunnel current!

STM arrives

Low-temperature scanning tunneling microscope (STM) installed, February 2019

Ultrafast laser arrives

40 W femtosecond laser and optical parameteric amplifier installed, October 2018

Lab renovations complete

Laboratory renovations completed, August 2018

Lab renovations begin

After extensive design work by Michigan State University Infrastructure Planning and Facilities and Prof. Cocker, renovations of the lab space for the Ultrafast Terahertz Nanoscopy Laboratory begin, January 2018

The Cocker Group is founded

Tyler Cocker moves to the Department of Physics and Astronomy at Michigan State University as an Assistant Professor, starting a new research group for Ultrafast Terahertz Nanoscopy on January 1st, 2018. The group will study ultrafast dynamics on the nano and atomic scales with a variety of techniques, including lightwave-driven terahertz scanning tunneling microscopy and terahertz spectroscopy.
