COHERENT INFRARED LASER.

Abstract

It is believed that in principle the Franck-Condon pumping technique can produce vibrational population inversions which are large enough to yield laser action. However, neither a molecule with a suitable metastable state, nor one which ionizes by a direct Franck-Condon process and has a vibrational dipole moment has been found. It is becoming clear that the mode of ionization of most molecules is not known. Experiments which can determine the mode of ionization of molecules are just now being undertaken in several laboratories. However, this type of experiment requires specialized equipment and techniques which are well beyond the scope of this contract. Work now under way elsewhere may lead to the identification of one or more molecular systems with suitable properties. When such an identification is made, it seems reasonable that work on a laser application might be resumed. (Author)
