Time-resolved photoemission spectroscopy (TRPES) implemented by femtosecond pulsed laser sources has become a powerful tool to investigate light-induced dynamics of matter from an electronic structural point of view. We here describe three types of TRPES apparatus developed at ISSP; namely, high-repetition-rate TRPES based on a Yb:fiber laser, high-energy-resolution TRPES based on a Ti:Sapphire laser, and extreme-ultraviolet TRPES based on high harmonics of 20-60 eV. The former two uses 5.9 eV pulses for the probe, and are suited for high precision measurements owing to their high repetition rate and high energy resolution of < 20 meV. The latter is suited for investigating far from equilibrium dynamics, and has the accessibility into core level spectra, full valence band, and entire Brillouin zone.
