Abstract
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.
