The investigation of possibilities to influence electrons in solids and at surfaces on the femtosecond (10-15 s) time scale is an important area of research. This is also relevant for the steering of magnetic switching processes by ultrashort laser pulses and for the control of the spin of excited electrons. At the MPI of Microstructure Physics, the control of the spin of optically excited photoelectrons is investigated by the absorption of multiple photons at metal surfaces.
