Paper Abstract

The hot holes population inversion (PI) and FIR amplification mechanism in germanium in crossed electric and magnetic fields at low temperature were proposed in 1979 [1]. The hot holes lasers were constructed for the first time in 1982 at LSTU [2]. The stimulated emission due to light holes (LH) - to heavy holes (HH) transitions (Fig.1) was observed later by Andronov with coworkers and Komiyama with coworkers [3]. The stimulated intersubband emission provided with nonselective resonator covers the spectral ranges λ = 80...120 and 150..210 μm.
