Abstract From the Canadian patent

Method and apparatus for inducing laser action in CO2 at a wavelength of 16 microns involving the transition between the 02°0 and 0110 states. The population inversion between these two states is achieved by pumping to the 00°1 level, suppressing the usual 10.6 micron transition to the 10°0 level and encouraging the 9.6 micron transition thereby populating the 02°0 level, as the principal prerequisite for 16 micron laser action between the 02°0 and 0110 levels.
