Abstract

A 2.5-THz heterodyne receiver has been realized in a pulse tube cooler. This liquid cryogen free system is based on a quantum cascade laser (QCL) acting as local oscillator and a hot electron bolometeric mixer. The double sideband noise temperature of the system is 2000 K and when corrected for optical losses in the signal path it is 800 K. A detailed study of the QCL beam quality yielded a beam propagation factor of 1.1-1.3.
