Isolated attosecond pulse,Attosecond pulse characterization

In this work, we utilized an all-optical method to measure the pulse width of isolated attosecond pulse. A 227 as and a 148 as duration pulse, with the center photon energy of 60 eV and 107 eV, respectively, were demonstrated by reconstructing the All-optical FROG trace using Least Squares Generalized Projections (LSGP) algorithm.
