Fig. 1: Energy-resolved attosecond angular streaking.
a Schematic of the experimental measurement with angular streaking. Energy-dependent photoelectron angular distribution acquired from (b) measurements; (c) numerical solution of TDSE; and (d) ICCSFA simulations. The white diamonds denote the measured or simulated MPEA of photoelectrons, and the white stars represent the simulated angle of the final momentum of the electron emitted at the instant of the electric field peak. The peak laser intensity is (45 ± 2) TW cm−2 for the measurements and 45 TW cm−2 for the simulations. The color bar stands for the normalized intensity of the measured or calculated photoelectron yields in logarithmic scale
