摘要
The spectrum of stimulated THz emission from uniaxially compressed p-Ge is presented. The peaks corresponding to different optical transitions from resonance to ground and excited states of an acceptor were observed in the spectrum of stimulated emission. The peaks were identified by means of a comparison of experimental data with calculated acceptor level positions in dependence on pressure. The mechanism of a population inversion due to free carrier accumulation near energies of resonance acceptor states based on the resonance scattering is proposed.
