Abstract
A CO.sub.2 medium is optically pumped by a five micron CO laser to the 03'0 level which radiates with 16 micron emission to the 02.degree.0 level. The resulting 16 micron laser finds application in laser uranium enrichment operating to provide excitation of uranium hexafluoride particles. Terminal level blockage, or bottlenecking, in the 02.degree.0 level is optionally avoided for continuous mode operation by 10 micron excitation with a CO.sub.2 laser from the 02.degree.0 to the 00.degree.1 level. The CO.sub.2 is then diluted by mixing nitrogen gas with it to promote energy transfer to the V=1 vibrational level of the nitrogen, thereby insuring maintenance of the inversion necessary for efficient, high power lasing in the 03'0 to 02.degree.0 transition.
