Thermal radiation, or any incoherent radiation at the desired wavelenths, is converted into laser energy by using radiant absorption from a radiation source by a cold gas. The cold gas absorbs vibrational energy while remaining otherwise cold, and exchange of vibrational energy between molecules at this low temperature causes population inversions.

Thermal-radiation excited vibrational-exchange pumped laser generator

When using CO as the absorbing and lasing species for vibration-vibration energy transfer and subsequent vibration-vibration pumping, CO can be made to dissociate and subsequently form C.sub.2 with isotope separation, or CO may be made to chemically react with N.sub.2 to produce CN with isotope separation.
