He-Ne lasers can provide three frequencies near 2.4 μm, one of which coincides with the1R(5)frequency of HF at 4173.98 cm-1. Either of the other frequencies may serve as a reference for absorbance measurements. One of these, at 4169.33 cm-1, is a new lasing transition not previously observed (4d'_{4}-3P_{9}). Operating conditions are discussed.
