The stimulated for infrared emission of a p-type-Ge cyclotron resonance laser is investigated in the frequency range between 60 cm[sup [minus]1] and 80 cm[sup [minus]1]. If the applied electric field is adjusted to achieve maximum output intensities, a single magnetic field tunable emission line is observed. By detuning the electric field a second line occurs in the laser spectrum. The presence of this line is governed by the amount of mixing between the Landau levels of the light and heavy holes induced by the electric field. From a comparison of the observed emission frequencies with calculated transition energies, a second laser transition is identified which appears in addition to the dominant n = 1 to n = 0 Landau level transition of the b-set.
