This chapter discusses terahertz radiation-induced saturation of absorption, including incoherent and coherent saturation effects. Saturation due to slow relaxation and Rabi oscillations in various bulk and low-dimension semiconductors is discussed from theoretical and experimental perspectives. It is shown that THz saturation experiments provide a powerful method for studying the kinetics and the details of the relaxation processes in bulk and low dimensional materials. In particular, spin relaxation times in low dimensional systems at monopolar spin orientation become experimentally accessible, which are of interest for the current topic of spintronics.Less
