GRK Colloquium:
Ultrafast nanoscopy experiments

June 14 @ 14:15 – 15:45

Markus Huber

Advancing optical microscopy to increasingly shorter length- and timescales has been a key process to visualize the connection between nanoscopic elementary dynamics and macroscopic functionalities of matter.

In this colloquium, I will give a basic introduction to the broad field of ultrafast nanoscopy. I will show different approaches of how ultrafast temporal resolution can be combined with nanoscale spatial resolution to see novel dynamics in a variety of materials. The focus will hereby be on coupling of light to sharp metallic tips, the fundamental approach for techniques like ultrafast near-field microscopy, lightwave scanning-tunneling microscopy and near-field optical tunneling emission microscopy.
