Measurement of Chemical Oxygen-Iodine Laser Singlet Oxygen Generator Parameter Using Raman Spectroscopy

Abstract

Using a doubled Nd:YAG laser as a spontaneous vibrational Raman scattering source, and a single intensified CCD array at the exit of an imaging monochromator, the Raman scattering system is used to directly measure the concentrations of the O2(alpha sup 1 delta) and the O2(X sup 3 Sigma)) in the chemical oxygen-iodine laser singlet oxygen generator in real time. We present the results from the tests that conducted on a 0.1 mol singlet oxygen-iodine generator. With the current reported uncertainty of the Raman cross-section, the error in the yield measurement is calculated to be less than 8%.
