Population inversion and amplification of far-IR radiation at cyclotron resonance of heavy hot holes in germanium
A new mechanism for the creation of a population inversion of holes in germanium, involving a cyclotron resonance of heavy hot holes, is discussed. The coefficient of amplification far-IR radiation is derived. The distribution function found for light hot holes by the Monte Carlo method turns out to be inverted at low hole energies. This inversion may also lead to a population inversion of the light holes in terms of Landau levels. The possibility of an experimental observation of stimulated emission is discussed.
