Abstract

Operation of the far-infrared gallium-doped p-type germanium laser in the broadband range above 70 cm-1, which requires relatively high magnetic fields, is demonstrated using novel permanent magnet assemblies. NdFeB and SmCo magnet assemblies were compared. The applied field from a NdFeB assembly was found to decrease strongly on cooling to the cryogenic temperature required for p-Ge laser operation, but that of a SmCo assembly changes insignificantly. © 2002 Elsevier Science B.V.
