Jitter correction for asynchronous optical sampling terahertz spectroscopy using free-running pulsed lasers
Mayuri Nakagawa, Natsuki Kanda, Toshio Otsu +3
We demonstrate a jitter correction method for asynchronous optical sampling (ASOPS) terahertz (THz) time-domain spectroscopy using two free-running oscillators. This method simulta…
A compact and stable incidence-plane-rotating second harmonics detector
S. H. Kim, S. Jung, B. Seok +6
We describe a compact and stable setup for detecting the optical second harmonics, in which the incident plane rotates with respect to the sample. The setup is composed of rotating…
Effect of the sample work function on alkali metal dosing induced electronic structure change
Saegyeol Jung, Yukiaki Ishida, Minsoo Kim +10
Alkali metal dosing (AMD) has been widely used as a way to control doping without chemical substitution. This technique, in combination with angle resolved photoemission spectrosco…
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…
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…
High repetition pump-and-probe photoemission spectroscopy based on a compact fiber laser system
Y. Ishida, T. Otsu, A. Ozawa +4
The paper describes a time-resolved photoemission (TRPES) apparatus equipped with a Yb-doped fiber laser system delivering 1.2-eV pump and 5.9-eV probe pulses at the repetition rat…
Emergent photovoltage on SmB6 surface upon bulk-gap evolution revealed by pump-and-probe photoemission spectroscopy
Y. Ishida, T. Otsu, T. Shimada +5
Recent studies suggest that an exemplary Kondo insulator SmB6 belongs to a new class of topological insulators (TIs), in which non-trivial spin-polarized metallic states emerge on…
