| Abstract: | We derive an analytical expression that relates the breadth of a streaked photoelectron spectrum to the group-delay dispersion
of an isolated attosecond pulse. Based on this analytical expression, we introduce a simple, efficient and robust procedure
to instantly extract the attosecond pulse’s chirp from the streaking measurement. We show that our method is robust against
experimental artifacts. |
