The patent application concerns a laser system and method for exciting lasing action in a molecular gas lasing medium. It involves cooling the lasing medium to a temperature below about 150$sup 0$K and injecting fission fragments through the lasing medium so as to preferentially excite low lying vibrational levels of the medium and to cause population inversions therein. The cooled gas lasing medium should have a mass areal density of about .005/mu/s cm$sup 2$, relaxation times of greater than 50 /mu/s, and a broad range of excitable vibrational levels which are excitable by molecular collisions. CO gas may be used. (NTIS)
