Abstract text (incl. figure legends and references)
While transmission electron microscopy (TEM) has evolved into a powerful tool for atomic-scale structure determination, temporal resolution in TEM has received far less attention, with detector and beam-current limits being on the order of microseconds. In this talk, I will describe how time resolution limits can be pushed by coupling ultrafast pulsed lasers to otherwise conventional TEMs. After briefly describing the experimental setup, I will present some of our recent work on transient lensing from photoemitted electron clouds on the picosecond time scale. I will also show how lasers coupled to TEMs can be used to induce nanoscale structural changes in nanomaterials on much slower time scales.
