Erich Rohwer

Erich Rohwer is Professor of Physics and Executive Head of the Physics Department at University of Stellenbosch, South Africa. His research develops advanced spectroscopic techniques including vacuum ultraviolet laser spectroscopy, second harmonic generation characterization, and ultrafast pump-probe methods for material analysis.

Research applies tunable VUV radiation from four-wave mixing processes to study molecular excitations in CO, including state-selective excitation and Rydberg state measurements. Additional work uses second harmonic generation for interface characterization in semiconductor materials and ultrafast electron diffraction for time-resolved structural analysis.
