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…
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…
Dispersion-free monochromatization method for selecting a single-order harmonic beam
Eiji J. Takahashi, Masatoshi Hatayama, Satoshi Ichimaru +1
We propose a method to monochromatize multiple orders of high harmonics by using a proper designed multilayer mirror. Multilayer mirrors designed by our concept realize the perfect…
Wavelength dependence of high-order harmonic generation with the ionization and ponderomotive energy controlled by an extreme ultraviolet pulse
Kenichi L. Ishikawa, Eiji J. Takahashi, Katsumi Midorikawa
We theoretically study the scaling with the driving wavelength of the high-order harmonic generation (HHG) under the simultaneous irradiation of an extreme ultraviolet (XUV) pulse.…
