1-MHz operation of 1.7-cycle multiple plate compression at 35-W average output power
Takuya Okamoto, Yoji Kunihashi, Yasushi Shinohara +3
We generated 1.7-cycle and 35-J pulses at a 1-MHz repetition rate by using two-stage multiple plate continuum compression of Yb-laser pulses with 80-W average input power. By ad…
Atomic real-space perspective of light-field-driven currents in graphene
Yuya Morimoto, Yasushi Shinohara, Kenichi L. Ishikawa +1
When graphene is exposed to a strong few-cycle optical field, a directional electric current can be induced depending on the carrier-envelope phase of the field. This phenomenon ha…
Asymmetric nonlinear optics of a polar chemical bond
Yuya Morimoto, Yasushi Shinohara, Mizuki Tani +3
A dielectric material's response to light is macroscopically described by electric displacement fields due to polarization and susceptibility, but the atomistic origin is light-cyc…
Time-dependent Hartree-Fock study of electron-hole interaction effects on high-harmonic generation from periodic crystals
Takuya Ikemachi, Yasushi Shinohara, Takeshi Sato +3
We investigate the multielectron effects on high-harmonic generation from solid-state materials using the time-dependent Hartree-Fock theory. We find qualitative change in harmonic…
Trajectory analysis of high-harmonic generation from periodic crystals
Takuya Ikemachi, Yasushi Shinohara, Takeshi Sato +3
We theoretically study high-harmonic generation (HHG) from solids driven by intense laser pulses using a one-dimensional model periodic crystal. By numerically solving the time-dep…
