Paper Abstract

In recent years it has become possible to achieve high power stimulated far infrared (FIR) radiation due to transitions between the light and heavy hole subbands of p-Ge crystals subjected to crossed electric (E) and magnetic (B) fields /1,2/. The population inversion arising between the light and heavy hole bands under such a crossed field situation has been qualitatively explained by a strong interaction of the heavy holes with optical phonons and an accumulation of light holes in momentum space /3/. According to this semiclassical picture, where the quantizing effect of the applied magnetic field is neglected, the expected stimulated emission is broadband and the obtained spectra should be independ of the values of the electric and magnetic field for a constant ratio E/B. In this work we present for the first time results of a detailed, systematic investigation of the dependence of the emission spectra of stimulated light-heavy hole emission on the absolute values of the electric and magnetic fields for a constant ratio E/B.
