A novel interband-pump intersubband-probe technique is developed in order to study the dynamics of photogenerated carriers and excitons in \(\mathrm{GaAs} / \mathrm{AlGaAs}\) superlattices by time resolved photoinduced absorption. The photogenerated population reaches a thermal distribution a few pi
