Modeling of jitter correction methods for asynchronous optical sampling
Mayuri Nakagawa, Natsuki Kanda, Ryusuke Matsunaga
Timing jitter management is crucial in asynchronous optical sampling (ASOPS) and dual-comb spectroscopy to maintain spectral bandwidth and fidelity. However, a quantitative framewo…
High-Field Terahertz Spin Resonance in CrO above the Spin-Flop Transition
Kaiyang Huang, Yuto Kinoshita, Natsuki Kanda +4
We report single-shot terahertz time-domain spectroscopy of CrO in pulsed magnetic fields up to 30 T. Well above the spin-flop field, in the 20-30 T range, the resonance fr…
Correction of broadband terahertz electro-optic sampling with GaSe crystals
Kotaro Ogawa, Natsuki Kanda, Yuta Murotani +3
Gallium selenide (GaSe) is an efficient nonlinear crystal for electro-optic (EO) sampling in the multi-terahertz (THz) frequency range. However, the lattice resonance at several TH…
Robust asynchronous optical sampling terahertz spectroscopy using commercially available free-running lasers
Mayuri Nakagawa, Natsuki Kanda, Hidekazu Nakamae +2
This study presents asynchronous optical sampling (ASOPS) terahertz spectroscopy using commercially available Ti:Sapphire lasers without stabilizing repetition frequency. Our postp…
Valley polarization dynamics of photoinjected carriers at the band edge in room-temperature silicon studied by terahertz polarimetry
Ami M. Shirai, Yuta Murotani, Tomohiro Fujimoto +3
Sixfold-degenerate valleys in Si have attracted considerable attention for valleytronics application. Using optical pump-terahertz (THz) probe spectroscopy, we study the dynamics o…
Light-induced inverse spin Hall effect and field-induced circular photogalvanic effect in GaAs revealed by two-dimensional terahertz Fourier analysis
Tomohiro Fujimoto, Yuta Murotani, Tomohiro Tamaya +7
The electromotive force transverse to a bias field under irradiation of circularly polarized light, namely the photovoltaic Hall response or light-induced anomalous Hall effect, ha…
Programmable generation of counterrotating bicircular light pulses in the multi-terahertz frequency range
Kotaro Ogawa, Natsuki Kanda, Yuta Murotani +1
The manipulation of solid states using intense infrared or terahertz light fields is a pivotal area in contemporary ultrafast photonics research. While conventional circular polari…
Emergence of high-mobility carriers in topological kagome bad metal MnSn by intense photoexcitation
Takuya Matsuda, Tomoya Higo, Kenta Kuroda +13
Kagome-lattice materials offer novel playgrounds of exploring topologically nontrivial states of electrons under influence of many-body interactions. A noncollinear kagome antiferr…
Anomalous Hall transport by optically injected isospin degree of freedom in Dirac semimetal thin film
Yuta Murotani, Natsuki Kanda, Tomohiro Fujimoto +7
Chirality of massless fermions emergent in condensed matter is a key to understand their characteristic behavior as well as to exploit their functionality. However, chiral nature o…
Time-domain characterization of electric field vector in multi-terahertz pulses using polarization-modulated electro-optic sampling
Natsuki Kanda, Mayuri Nakagawa, Yuta Murotani +1
We demonstrated characterizing the electric field waveform of multi-terahertz pulses (10-50 THz) as vector quantities in the time domain by applying the polarization modulated elec…
