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…
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…
Generation of subcycle isolated attosecond pulses by pumping ionizing gating
Zhaohui Wu, Hao Peng, Xiaoming Zeng +11
We present a novel approach named as pumping ionizing gating (PIG) for the generation of isolated attosecond pulses (IAPs). In this regime, a short laser is used to ionize a pre-ex…
A custom-tailored multi-TW optical electric field for gigawatt soft-x-ray isolated attosecond pulses
Bing Xue, Yuuki Tamaru, Yuxi Fu +6
The bottleneck for an attosecond science experiment is concluded to be the lack of a high-peak-power isolated attosecond pulse source. Therefore, currently, generating an intense a…
Nonlinear terahertz-wave radiation generated by mid-infrared dual-chirped optical parametric amplification femtosecond pulse laser excitation
Kyuki Shibuya, Kouji Nawata, Yoshiaki Nakajima +5
We demonstrate an efficient procedure for terahertz-wave radiation generation by applying a nonlinear wavelength conversion approach using a mid-infrared pump source. We used a 3.3…
Apparatus for generation of nanojoule-class water-window high-order harmonics
Kotaro Nishimura, Yuxi Fu, Akira Suda +2
In our recent study [Commun. Phys. 3, 92 (2020)], we have developed an approach for energy-scaling of high-order harmonic generation in water-window region under neutral-medium con…
Energy scaling of water window high-order harmonic generation for single-shot soft X-ray spectroscopy and live-cell imaging
Yuxi Fu, Kotaro Nishimura, Renzhi Shao +4
Full coherent soft X-ray attosecond pulses are now available through high-order harmonic generation (HHG); however, its insufficient output energy hinders various applications, suc…
Fully stabilized multi-TW optical waveform synthesizer for gigawatt soft-x-ray isolated attosecond pulses
Bing Xue, Yuuki Tamaru, Yuxi Fu +6
A stable 50 mJ three-channel optical waveform synthesizer is demonstrated and used to reproducibly generate a high-order harmonics supercontinuum in the soft-x-ray region. This syn…
Optimization of a multi-TW few-cycle 1.7-m source based on Type-I BBO dual-chirped optical parametric amplification
Lu Xu, Kotaro Nishimura, Yuxi Fu +3
This paper presents the optimization of a dual-chirped optical parametric amplification (DC-OPA) scheme for producing an ultrafast intense infrared (IR) pulse. By employing a total…
