WebbJ. C. Polanyi first proposed a chemical laser in 1960 by recognizing that many chemical reactions deposit excess energy in the stretching vibrations of the newly formed bond. If the chemical reaction favors the production of states with greater internal energy over states with less internal energy, then a population inversion can be achieved.
