The method of intracavity laser spectroscopy using a Co:MgF2 laser is applied to record the absorption spectra from the first excited a1Dg state of gaseous molecular oxygen at the a1Dg b1Sg+ transition at 1.91 mm. The gas flow from a chemical singlet oxygen generator with a known concentration of singlet oxygen O2 (a1Dg) was supplied to the cavity of the Co:MgF2 laser. The absorption line intensities are measured for five spectral lines of the Q-branch of the 00 vibrational band for the a1Dg b1Sg+ transition. The O2 (b1Sg+ a1Dg) transition probability calculated from these data was (1.20 ± 0.25) × 10-3 s-1. |
