Intersubband (ISB) transitions in semiconductor multi-quantum well (MQW) structures are promising candidates for the development of saturable absorbers at terahertz (THz) frequencies. Here, we exploit amplitude and phase-resolved two-dimensional (2D)

The low-temperature relaxation processes of non-equilibrium holes into gallium centers in moderately doped p-germanium (NA ≈ 2×10^15 cm-3) has been investigated by a degenerate pump-probe experiment using the free electron laser FELBE. The capture
