Abstract
We report of a easy-to-use terahertz radiation source, which combines a QCL operating at 3.1 THz with a compact, low-input-power Stirling cooler. The QCL, which is based on a two-miniband design, has been developed for high output powers and low electrical pump power. The whole system weighs less than 15 kg including cooler, power supplies etc. The peak output power is 8 mW at 3.1 THz. The applicability of the system is demonstrated by imaging and molecular spectroscopy experiments.
