We have stabilized the frequency of a 3.1THz quantum cascade laser (QCL) to the rotational transition J=2726 of carbon-monoxide (CO).
The achieved frequency stability was 5 x 10^{-9} in the Allan standard deviation at 10s averaging time.
The absolute frequency of the THz-QCL was determined to be 3 097 909.4(0.1)MHz, which agrees to the previous report within the uncertainty. This CO-stabilized THz-QCL has a potential to be served as an unprecedented frequency standard in THz region.
