Population Trap in X-ray-induced Ultrafast Nonadiabatic Dynamics of Tropone Probed at the O(1\textit{s}) pre-edge
Kaoru Yamazaki, Katsumi Midorikawa
Nonadiabatic transition (NAT) drives a variety of x-ray-induced photochemistry and photophysics used in nature and various fields. To clarify the x-ray-induced NAT dynamics, we per…
100-mJ class, sub-two-cycle, carrier-envelope phase-stable dual-chirped optical parametric amplification
Lu Xu, Bing Xue, Nobuhisa Ishii +3
Based on the dual-chirped optical parametric amplification and type-I BiBO(BiBO) crystals, the generation of 100 mJ, 10.4 fs, 10 Hz, carrier-to-envelope phase (CEP)-stab…
Advent of a gigawatt-class, tabletop, isolated-attosecond-pulse light source
Bing Xue, Katsumi Midorikawa, Eiji J. Takahashi
We have produced a soft x-ray supercontinuum with a pulse energy of 0.24-J using high-order harmonics from a multiterawatt, 10-Hz, stable, three-channel waveform synthesizer [Sc…
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…
