An optical frequency comb has been used to measure the frequency of a diode laser system, locked to the P(10), P(11), P(15), P(16), P(20), and P(21) transitions in the ν13 overtone band of 13C2H2. When locked to any of these transitions, the laser frequency showed a stability of 4×10-12 in 1 s and a reproducibility of better than 1 kHz. The frequency of the reference P(16) transition was found to be P(16)=194369569383.83 kHz with an uncertainty of 0.32 kHz, based on measurements of a single system, and 2.5 kHz, based on the reproducibility of independent systems.
