Time-, spin-, and angle-resolved photoemission spectroscopy with a 1-MHz 10.7-eV pulse laser
Kaishu Kawaguchi, Kenta Kuroda, Z. Zhao +12
We describe a setup of time-, spin-, and angle-resolved photoemission spectroscopy (tr-SARPES) employing a 10.7-eV (=115.6 nm) pulse laser at 1-MHz repetition rate as a probe ph…
Spin-polarized saddle points in the topological surface states of the elemental Bismuth revealed by a pump-probe spin-resolved ARPES
Yuto Fukushima, Kaishu Kawaguchi, Kenta Kuroda +11
We use a pump-probe, spin-, and angle-resolved photoemission spectroscopy (ARPES) with a 10.7 eV laser accessible up to the Brillouin zone edge, and reveal for the first time the e…
Stimulated Rayleigh Scattering Enhanced by a Longitudinal Plasma Mode in a Periodically Driven Dirac Semimetal CdAs
Yuta Murotani, Natsuki Kanda, Tatsuhiko N. Ikeda +6
Using broadband (12-45 THz) multi-terahertz spectroscopy, we show that stimulated Rayleigh scattering dominates the transient optical conductivity of cadmium arsenide, a Dirac semi…
Work function seen with sub-meV precision through laser photoemission
Y. Ishida, J. K. Jung, M. S. Kim +7
Electron emission can be utilised to measure the work function of the surface. However, the number of significant digits in the values obtained through thermionic-, field- and phot…
100 MHz high-speed strain monitor using fiber Bragg grating and optical filter applied for magnetostriction measurements of cobaltite at magnetic fields beyond 100 T
Akihiko Ikeda, Toshihiro Nomura, Yasuhiro H. Matsuda +4
High-speed 100 MHz strain monitor using fiber Bragg grating (FBG) and an optical filter has been devised for the magnetostriction measurements under ultrahigh magnetic fields. The…
High-speed 100 MHz strain monitor using fiber Bragg grating and optical filter for magnetostriction measurements under ultrahigh magnetic fields
Akihiko Ikeda, Toshihiro Nomura, Yasuhiro H. Matsuda +4
A high-speed 100 MHz strain monitor using a fiber Bragg grating, an optical filter, and a mode-locked optical fiber laser has been devised, which has a resolution of $ΔL/L\sim10^{-…
Time-resolved photoemission apparatus achieving sub-20-meV energy resolution and high stability
Y. Ishida, T. Togashi, K. Yamamoto +5
The paper describes a time- and angle-resolved photoemission apparatus consisting of a hemispherical analyzer and a pulsed laser source. We demonstrate 1.48-eV pump and 5.90-eV pro…
