Abstract

We report on development of a turn-key, cryogen-free bulk p-Ge laser which is broadly tunable over the range 1.5 to 4.2 THz. A 4 K closed cycle refrigerator was used to eliminate the need for liquid cryogen. A SmCo permanent magnet assembly provides the necessary magnetic field for the laser. A customized high voltage (HV) power supply and thyratron pulser were developed to replace the stack of general electronics previously used to operate the laser.
