Available in PDF, EPUB and Kindle. Book excerpt: Finally, in order to temporarily characterize the attosecond pulses we designed and built an "Attosecond Streak Camera". Most of such cameras to date are limited to measuring a 1 dimensional energy spectrum and have only a few degrees of acceptance angle. Our camera is capable of measuring 2d momentum of the photoelectrons with large acceptance angle, for example ∼65° at the photoelectron of energy ∼15 eV. Recently, we observed the sidebands in addition to the main peaks in their laser assisted XUV photoelectron spectrum. The single attosecond pulses, after being characterized with this high speed camera, can be used to explore the dynamics of electrons at the attosecond scale.
