The method of intracavity laser spectroscopy using a Co:MgF{sub 2} laser is applied to record the absorption spectra from the first excited a{sup 1{Delta}}{sub g} state of gaseous molecular oxygen at the a{sup 1{Delta}}{sub g} {yields} b{sup 1{Sigma}}{sub g}{sup +} transition at 1.91 {mu}m. The gas flow from a chemical singlet oxygen generator with a known concentration of singlet oxygen O{sub 2} (a{sup 1{Delta}}{sub g}) was supplied to the cavity of the Co:MgF{sub 2} laser. The absorption line intensities are measured for five spectral lines of the Q-branch of the 0-0 vibrational band for the a{sup 1{Delta}}{sub g} {yields} b{sup 1{Sigma}}{sub g}{sup +} transition. The O{sub 2} (b{sup 1{Sigma}}{sub g}{sup +} {yields} a{sup 1{Delta}}{sub g}) transition probability calculated from these data was (1.20 {+-} 0.25) x 10{sup -3} s{sup -1}.
