Femtosecond Nonlinear Optical Spectroscopy of Nanoscale Materials

Ongoing
The purpose of this project is to develop and refine spectroscopic techniques based on nonlinear optics for the study of novel materials. Measurements that isolate the nonlinear response are often better able to uncover physical processes that, in the linear response, are subtle and hard to isolate

Beamline 7: EUV reflectometry

The NIST/DARPA EUV Reflectometry facility began in the late 1980's to make measurements of the reflectivity of EUV multilayer optics for lithography. Since then
