Complex-gate all-optical frequency-resolved optical gating for ultrabroadband isolated attosecond pulse characterization
Minshuang Xia, Kaito Nishimiya, Dianhong Dong +2
We experimentally demonstrate all-optical frequency-resolved optical gating (AO-FROG) for the characterization of ultrabroadband isolated attosecond pulses (IAPs) generated by a mi…

Submicrometer focusing of isolated attosecond XUV pulses approaching 10 W/cm
Kotaro Imasaka, Dianhong Dong, Natsuki Kanda +6
We demonstrate submicrometer focusing of isolated attosecond pulses (IAPs) in the extreme ultraviolet (XUV) region using a custom ellipsoidal mirror. The obtained focal spot sizes…

Perturbed three-channel waveform synthesizer for efficient isolated attosecond pulse generation and characterization
Dianhong Dong, Hushan Wang, Bing Xue +5
The generation of gigawatt-class isolated attosecond pulses (IAPs) is vital for attosecond pump-probe experiments. In such experiments, the temporal duration of IAPs must be determ…
