I hereby report on the forthcoming development of non-linear coherent spectroscopy in the extreme ultraviolet (EUV) and soft x-ray range at the FERMI free-electron laser (FEL) facility. This class of experiments is routinely used in the optical domain, where fully coherent photon sources (i.e., lasers) are available. These methods have not yet developed in the EUV/x-ray range, since photon sources having characteristics comparable with those of table-top lasers were not available so far. Such a void is being filled by seeded FELs sources, such as FERMI, which are in many respects similar to conventional lasers. EUV/soft x-ray non-linear coherent spectroscopy will be initially focused on the study of collective atomic dynamics in disordered systems. However, recent advances achieved at FERMI, such as the capability to radiate multiple and multi-color seeded FEL pulses, opens up the possibility to largely extend the possible applications of such experimental techniques.
