Nonlinear Quantum Transport with the UCSB Free-electron Lasers

The UCSB free-electron lasers deliver kilowatts of terahertz radiation that can be tuned from 120 GHz to 5 THz. They provide an opportunity that is unique in the world to explore the non-linear response of semiconductor nanostructures and other systems.
