ABSTRACT:
CW laser action achieved on the .sup.2P 178-.sup.2P 3/2 transition of the iodine atom by energy transfer from the .sup.1 .DELTA. metastable state of O.sub.2. The effluent from a conventional oxygen generator was mixed with molecular iodine at the entrance of a longitudinal flow laser cavity where the I.sub.2 was dissociated by a small amount of O.sub.2 (.sup.1 .SIGMA.) that was present in the flow due to energy pooling processes. The measured output power was greater than 4mW.
