Experimental evidence is presented for stimulated far-infrared emission from population-inverted hot-carrier system in p Ge. The spectroscopic study by use of an n-InSb cyclotron-resonance detector reveals that the spectrum of the emission consists of a fairly sharp band located at the photon energy ∼5 or ∼10 meV depending on the applied fields.

    Investigations of the dynamics of the far-infrared p-Ge laser emission reveal strong periodic soliton-like intensity spikes with less than 100 ps duration. We interpret these spikes as self-mode-locking of p-Ge laser modes. The effect becomes more pronounced when a GaAs/AlGaAs/InGaAs quantum...
