In this chapter we will restrict our discussion to third order processes, which will be described by Four Wave Mixing (FWM) mechanism. In FWM one can generally distinguish two steps: a first step in which a coherent material excitation is performed and a second step in which the excitation is interrogated, yielding a signal wave (fourth wave) in which all information about the dynamics and the energy of the excitation is inherent.
