The results are given of an investigation of the conditions for efficient lasing, utilizing unconventional transitions in TEA CO/sub 2/ lasers. The following bands were considered: 00/sup 0/2--(10/sup 0/1, 02/sup 0/1)/sub i/,II (lambda = 9.2--10.8 ..mu..); (10/sup 0/1, 02/sup 0/1)/sub i/,II--(10/sup 0/0, 02/sup 0/0)/sub i/,II (lambda = 4.3 ..mu..); 01/sup 1/1--(11/sup 1/0, 03/sup 1/0)/sub i/ (lambda = 10.8--11.4 ..mu..). In the case of the 01/sup 1/1--(11/sup 1/0, 03/sup 1/0)/sub i/ and 00/sup 0/2--(10/sup 0/1, 02/sup 0/0)/sub i/,II transitions, a lasing efficiency of 35--52% of that for the regular band was obtained experimentally. The results are given of investigations of lasing in the wavelength range 11.45--11.85 ..mu.. (01/sup 1/1--(11/sup 1/0, 03/sup 1/0)/sub i/ band) using the isotopically substituted molecules /sup 13/CO/sub 2/.
