Abstract
PTB and DLR join their expertise and experience in optical radiometry and in THz techniques to perform what is to our knowledge the first traceable measurement of radiant power of a THz quantum cascade laser (QCL) and the first absolute calibration of a THz-radiation detector against a cryogenic radiometer. This paves the way for comparable, accurate and reliable power measurements strongly missing throughout the THz community.
