Title: Method of molecular specie alteration by nonresonant laser induced dielectric breakdown

Abstract

Irradiation of a molecular specie by itself or in the presence of a secondary material at a pressure above a threshold value for the particular system by a laser of predetermined minimum power and having a frequency displaced from an absorption line of the specie causes severance of the weakest bond and a yield of products containing at least one dissociative fragment from said specie. A Rogowski type TEA CO.sub.2 --N.sub.2 --He laser has been used successfully on a wide variety of molecular species. Solid, liquid and gaseous end products have been obtained depending upon the starting materials. When solids have been produced they are in the form of microfine particles or microfine aggregates. A neodymium glass laser has also been used successfully.
