Abstract
Lasers are disclosed wherein trapped multiline laser radiation from a DF laser is employed to pump a DF-CO.sub.2 working gas mixture within the optical resonator for the DF laser. The multiline pumping energy is resonantly absorbed by the DF component of the working gas mixture and collisionally transferred to upper energy levels of lasing transitions in CO.sub.2. A narrow-band optical resonator disposed about the working gas interaction region with the pumping radiation and tuned to a desired CO.sub.2 transition enables a single line laser output to be obtained on the desired transition.
