The Copper-Doped p-Ge THz Laser in the Voigt Configuration: Possibility of Mode-Locked Operation

Abstract

We have constructed a copper-doped germanium hot hole THz laser and studied its performance under normal - pulsed - operation, in order to investigate the possibility to create very short "quasi monochromatic" pulses through active mode-locking. The E and B field region for which normal "long pulsed " laser emission occurs, emission wavelength as a function of B field and the temporal shape of the laser pulse have been studied. The results indicate that the performance of this Ge:Cu crystal can not yet compete with that of an earlier studied Ge:Ga laser under similar conditions. Nevertheless active mode-locking has already been observed.
