Abstract

An inversion between Landau levels (LL’s) of the light hole subband of germanium is achieved when the crystal is subjected to crossed electric and magnetic fields.^[1] This leads to stimulated far infrared (FIR) emission at the cyclotron resonance (CR) frequency. The emission spectrum consists of a single line linearly tunable with magnetic field (Fig. 2).^[2]
