Abstract
We present high resolution saturation spectra of $^{32}SF_{6}$, obtained with a $CO_{2}$ waveguide Laser over 500 MHz tuning ranges, for the P(12), P(14), P(16), P(18) P(20) lines of the 10.4 $\mu m$ band of $CO_{2}$. The peak-to-peak linewidth is of the order of 20 kHz. Frequency differences have been measured by beating the waveguide laser locked to one $SF_{6}$ resonance and a conventional low-pressure laser locked to a reference peak with an accuracy of $\pm$10 kHz for isolated lines. A theoretical fit, including terms up to true $2^{nd}$ order in Amat-Nielsen ordering scheme, has bean obtained for 72 lines with a standard deviation of approximately 500 kHz.
