Abstract :
A proof of principle experiment to evaluate the efficacy of CO and H/sub 2/O in increasing the power output for N/sub 2/O and CO/sub 2/ lasing mixtures has been conducted and theoretically analyzed for a blackbody radiation-pumped laser. The results for N/sub 2/O-CO, CO/sub 2/-CO, N/sub 2/O-H/sub 2/O and CO/sub 2/-H/sub 2/O mixtures are presented. Additions of CO to the N/sub 2/O lasant increased power up to 28% for N/sub 2/O laser mixtures, whereas additions of CO to the CO/sub 2/ lasant, and the addition of H/sub 2/O to both the CO/sub 2/ and N/sub 2/O lasants, resulted in decreased output power.<>
