Abstract :
We present experimental and theoretical results for the measurement of RGD of molecular gas absorption lines, which have the potential to be stable and well-characterized standards. We show the experimental apparatus we constructed for measuring group delay. We used an extended-cavity diode laser having a 80 nm tuning range centered at 1560 nm, with a single mode linewidth of 5 MHz in a one-second time interval.
