Current projects: Use of IR imaging in emergency room triage. Measurement of bilirubin in neonatal care

Prof. Guenther uses femtosecond pulsed laser systems to study ultrafast phenomena. Current research includes characterization of quantum well devices, development of terahertz electronics, and analysis of bunched relativistic electron beams. Because these projects are of fundamental interest to physicists, engineers, and material scientists, Dr. Guenther's research involves collaboration with other departments at Duke and other major universities. He is presently working on the application of femtosecond technology to the study of solids, the development of terahertz sources, and new measurement techniques associated with electron beams. He has used a Michaelson Interferometer to observe the temporal characteristics of the electron-beam used in the FEL.
