The lasing spectra and energy characteristics were investigated for lasers operating with the isotopes /sup 12/C/sup 16/O/sub 2/, /sup 13/C/sup 16/O/sub 2/, /sup 12/C/sup 18/O/sub 2/, and /sup 12/C/sup 16/O/sup 18/O. It was found that the output power of a laser utilizing the CO/sub 2/ isotopes was determined by the content of a particular isotope in the carbon dioxide gas. For equal enrichments, all the isotopes investigated, with the exception of /sup 12/C/sup 16/O/sup 18/O, gave comparable output powers. The unsaturated gains were identical for the most intense transitions of the symmetric molecules; the gain was a factor of two less for the asymmetric molecule. The gain rose linearly with increasing enrichment. The ultimate specific power output, given by the product of the saturation power density and the gain, was practically independent of the enrichment.
