A spontaneous Raman imaging System (SRIS) has been developed that can
monitor chemical oxygen-iodine laser (COIL) singlet oxygen generator (
SOG) performance in real time. This system permits one to monitor dire
ctly the SOG performance by measuring O-2(a(1) Delta) and O-2(X-3 Sigm
a) simultaneously with a single intensified CCD allay at the exit of a
n imaging monochromator. We present the results from tests conducted o
n a 0.25-mol SOG using a prototype Raman system. Performance and valid
ation of a highly sensitive SRIS that was designed and built specifica
lly for SOG diagnostics are discussed. Detection and possible interfer
ences of other species relevant to COIL devices such as I-2 and Cl-2 a
re investigated. (C) 1998 Optical Society of America.
