Terahertz heterodyne mixing with a hot electron bolometer and a quantum cascade laser

Heterodyne measurements in the frequency range between 1 - 6 terahertz (THz) are expected to provide a wealth of information on questions ranging from the formation of new stars and the conditions under which life formed on our own planet to the ozone hole in our own atmosphere. Hot electron bolometers (HEB) are currently the only suitable...
