Time resolved peem

Compared to many other electron microscopy techniques, time-resolved PEEM offers a very high temporal resolution of only a few femtoseconds with prospects of advancing it to the attosecond regime. The reason is that temporal electron pulse broadening does not deteriorate the temporal resolution because electrons are only used to achieve a high spatial resolution. The temporal resolution is reached by using very short light pulses in a pump-probe setup. A first pulse opticall… WebSep 7, 2007 · If this is the first time you used this feature, you will be asked to authorise Cambridge Core to connect with your Dropbox account.
