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...

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...
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 (...
This research thrust has the broad goal of capturing and manipulating coupled electron and nuclear dynamics in molecules by combining ultrafast X-ray and laser pulses with advanced molecular imaging techniques. This work will help address...
The quest to understand structure, dynamics and function at the nanoscale continues to drive new ultrahigh-resolution imaging technologies. Rapid progress in the past five years has laid the foundation for revolutionary new optical...
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...
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...
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...
Ultrafast laser pulses have greatly impacted our understanding of nature at the fundamental time scales relevant to atomic and molecular processes. Our research group has been a leader in this femtosecond laser science - advances from our...
