Measurements of the Yield and Chlorine Utilization of Singlet Oxygen Generator by Use of Raman Spectroscopy

A Raman scattering system was used to measure the O2 (a1 ?) yield and the chlorine utilization in a singlet oxygen generator of chemical oxygen iodine laser with nitrogen diluent. We present the results from the tests that conducted on a 0.1-mol /s jet-type singlet oxygen-iodine generator. On the basis of the current reported uncertainty of the Raman cross section, the error in the yield measurement is calculated to be less than 8%, and the error of the chlorine utilization is 12%.
