Abstract

Discrete lines with frequencies corresponding to the optical transitions from excited to ground states of acceptor impurity have been discovered in the radiation spectra of FIR pulsed hot hole p-Ge laser [1]. The main reason for lasing is light to heavy hole transitions gain. The population inversion arises due to the light holes accumulation in crossed electric and magnetic fields at helium temperatures. The experimental results show the additional amplification on the transitions between excited and ground states of acceptor impurity.
