The Kapteyn-Murnane Group

The thrust of research in our group is in optical and x-ray science using new tabletop light sources. We develop these new ultrafast laser and coherent x-ray sources as part of our research in optical science, and then make use of these light sources for new experiments in physics, chemistry, materials science and engineering. Since x ray techniques are...

Attosecond Nonlinear Optics
Ever since the invention of the visible laser 50 years ago, scientists have been striving to create lasers that generate coherent beams at shorter wavelengths i.e. the x-ray region of the spectrum. This quest has led to the construction of...

Ultrafast Magnetics
Magnetism has been the subject of scientific inquiry for more than 2000 years; however, it is still an incompletely understood phenomenon. The fundamental length and time scales for magnetic phenomena are nanometers (nm) and femtoseconds (...

Nanoscale Energy Transport
Thermal transport in nano structures is significantly different from macro scale transport due to the fundamental scale length of the energy carriers, set by both classical and quantum size effects. Thermal energy is carried by phonons...

Ultrafast Surface Science
A large fraction of chemical reactions of interest to technology and the environment are catalytic, with the reaction happening on a surface. These reactions are often mediated by electron charge transfer dynamics that occur on extremely...

Nanoscale Acoustic Metrologies
Surface Acoustic Waves (SAWs) are surface-confined elastic oscillations that are of great interest because of their high sensitivity to the mechanical properties of the material in which they propagate. Their penetration depth...
