Title: Metal atom oxidation laser

Abstract

A chemical laser which operates by formation of metal or carbon atoms and reaction of such atoms with a gaseous oxidizer in an optical resonant cavity is described. The lasing species are diatomic or polyatomic in nature and are readily produced by exchange or other abstraction reactions between the metal or carbon atoms and the oxidizer. The lasing molecules may be metal or carbon monohalides or monoxides. (auth)

  • A chemical laser which operates by formation of metal or carbon atoms and reaction of such atoms with a gaseous oxidizer in an optical resonant cavity is described. The lasing species are diatomic or polyatomic in nature and are readily produced by exchange or other abstraction reactions between the metal or carbon atoms and the oxidizer. The lasing molecules may be metal or carbon monohalides or monoxides.
  • A continuation of research investigating the feasibility of a metal atom oxidation laser is presented. The work was done on a metal-atom oxidation laser set-up which was designed and constructed as part of previous thesis research. The series of experiments was conducted with ten rare earth elements in a pure oxygen environment. A brief discussion of the toxicity and handling characteristics of the rare earth elements, the metal oxide laser system, and the possible metal deposition techniques is presented. The technique finally used in the metal deposition process and the difficulties incurred with this technique are also discussed. Although nomore » positive lasing action was noted, results from these experiments suggest further investigation is warranted.« less
  • A process for producing electric current by the electrochemical oxidation of an active anodic metal dispersed in an alkaline electrolyte is described. The electrolyte is circulated into contact with a second metal which is more electronegative than the active metal. A displacement reaction precipitates the active metal from its soluble oxidation products. There is obtained as a result a repeated recovery for reuse of the active metal (zinc) with the aid of the more electronegative metal (aluminum), which then supplies the energy for the production of current and is oxidized to form soluble products. The process is exemplified by zincmore » as the active metal and aluminum and magnesium as the strongly electronegative metals. 1 fig.« less
