BETTER THAN CAMERA, CLOCK OR RABBIT: A NOVEL TOOL FOR ATTOSECOND METROLOGY AT FEL

Wednesday, July 6, 2022 - 3:00pm

Speaker:  Anatoli Kheifets, ANU

Program Description:

Attosecond angular streaking of XUV ionization can characterize the shape, magnitude and spectral content of a single FEL shot. This technique combines an attosecond streak camera and an attoclock in one measurement. We expand this technique to tell the time of atomic and molecular photoionization. In this capacity, it competes well with the most accurate determination using reconstruction of attosecond beating by interference of two-photon transitions (RABBITT).  Under favourable conditions, the ionization timing can be determined on a shot-to-shot basis. Examples of atomic and molecular hydrogen are considered in our numerical demonstrations.
