WebRef. [15]. For the time-resolved Faraday rotation (ΔθF) and pump-probe transmission (ΔT/T) measurements, a Ti:sapphire regenerative amplifier system (1.55 eV, 100 fs, and 1 KHz) was used to excite an optical parametric amplifier. Time resolution of the measurement system is ~200 fs. The pump fluence at the sample surface was WebApr 26, 2005 · A time-resolved Faraday rotation magnetometer using externally triggered pulsed diode lasers is described. This device permits measurement of the dynamic properties of polarized electronic spins in semiconductors. A non- equilibrium spin polarization is created in the conduction band electrons of i}n-type GaAs using a circularly …
Femtosecond time-resolved Faraday rotation in thin magnetic …
WebBy acquiring time-resolved circular differential scattering signals we show that the spectral interpretation is significantly simplified. We experimentally demonstrate the equivalence between time-averaged chiral spectra observed for an individual nanostructure and the corresponding ensemble spectra, and thereby demonstrate the ergodic principle for … WebDec 14, 2015 · We study the exciton valley relaxation dynamics in single-layer ${\\mathrm{MoS}}_{2}$ by a combination of two nonequilibrium optical techniques: time-resolved Faraday rotation and time-resolved circular dichroism. The depolarization dynamics, measured at 77 K, exhibits a peculiar biexponential decay, characterized by two … indiana partnership withholding tax
