Abstract: Spatially encoded measurements of transient optical transmissivity became a standard tool for temporal diagnostics of free-electron-laser (FEL) pulses, as well as for the arrival time measurements in X-ray pump and optical probe experiments. The modern… read more here.

DOI: 10.1063/1.5131257
Abstract: We investigate the anharmonic effects in Bi2Se3 crystals using femtosecond transient optical spectroscopy at 5–280 K. The reflectivity time series consist of exponential decay due to hot carriers and decaying oscillations due to the A 1… read more here.
