Abstract
FIR/sub-mm laser emission (70 to 250 micron) from p-Ge in E⊥b fields is enhanced in Voigt-configuration. A spectrum of laser emission (Fig. 1) shows a few sharp modes at 170-200 µm. We recently demonstrated that permanent magnets provide an easier realization of the Voigt configuration than do the traditional superconducting solenoids [1,2], and a significant increase in the allowed electric-field range and output energy were observed. We report here an additional advantage which derives from the relatively open permanent magnet architecture. Large Cu blocks can be pressed in contact with two faces along the full 5 cm length of the Ge rod.
