Helping you understand, create, and characterize nanomaterials

Ultrafast Broadband Optical Spectroscopy

A suite of ultrafast excitation and diagnostic capabilities spanning wavelengths from the ultraviolet to the far-infrared are available for dynamic nanoscale characterization

Ultrafast spectroscopy provides important information about the excitation and relaxation dynamics occurring in complex nanomaterials. These capabilities enable coherent quantum control experiments, as well as experiments for dynamic materials characterization.

Capabilities include:
