-Frequency stabilization of a 1.55 µm DFB laser diode has been demonstrated by using the vibrational-rotational absorption of 13C2H2 molecules. Frequency stability to within 2 MHz peak/peak fluctuation was achieved at 1.54949 µm. The square root of the Allan variance σ(2, τ) of frequency fluctuation was calculated to be about 7 x 10-10for an averaging time of 0.05s < r < 100 s.
