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.
