Abstract
Theoretical and experimental investigations of the resonant amplification of far-infrared (FIR) radiation by hot holes in germanium in theE ⊥B field configuration have shown that stimulated emission is possible not only at the fundamental but also at higher harmonics of the light-hole cyclotron resonance frequency. Single line tunable FIR laser oscillations close to the fundamental and the second cyclotron harmonic are demonstrated and explained within the presented model. In the crossed field configuration a repulsion of light and heavy hole levels is predicted as a result of interaction.
