Abstract

Spin-polarized electron kinetics is studied by time-resolved polarized photoemission with picosecond resolution. The response time of strained layer photocathodes is found to be in a range of a few picosecond offering an ultrafast response and high spin-polarization of emitted electrons. The studies of the sub-picosecond spin dynamics are facilitated in high-intensity excitation regime when the length of the emission pulse is enlarged due to the dispersion of acceleration time and Coulomb repulsion of the electrons in their flight in the vacuum.
