In this thesis, the charge and spin transport properties in three-dimensional topological insulators and Weyl semimetals are investigated. The work comprises a theoretical part, which introduces the physical background of charge and spin transport in topological materials, and an experimental part, which covers different combined polarization and time-resolved optoelectronic spectroscopy methods. With this combined approach, we can uncover several novel spin and charge transport phenomena in topological materials. These include the spin Hall effect in topological insulators and a photoinduced anisotropic Hall effect in Weyl semimetals as well as a conductance quantization in topological surface states.
