Quantum effects stemming from a mixing of the states of light and heavy holes in p-Ge in fields E1H are shown to play an important role in the formation of population inversions and lasing in the cases of both intraband and interband hole transitions. These effects become sharply more important when the anisotropy of the valence band is taken into account.
