Abstract :
A THz synthesizer has been realized by phase locking the photomixer pump lasers to a frequency comb effectively locking the THz emission frequency of the source. This allowed the centre frequency of a molecular transition at 813 GHz to be measured with an accuracy of 20 kHz, (Δv/v ≈10-8).
