Laser performance at power levels up to 5 kW have been demonstrated for run times extending to 1 minute. Parametric studies of chlorine utilization and excited oxygen yield are presented for a wide range of operating conditions. Substantial degradation of the utilization is found as a function of accumulated KCl in the generator. Important water vapor density is inferred from pressure increase in the cavity when power extraction is inhibited. A new small scale disk generator driven by BHP flow only, is presented. Evaluation of processing costs shown industrial potential of COIL.
