OH/OD CW Chemical Laser Studies and New Supersonic Flow Laser Geometries. Part I. OH Chemical Laser Studies.

Abstract

The objective of this program was to develop a continuous wave chemical laser using OH or OD as the lasing species. Chemi-excited OH(OD) was produced by reaction of hydrogen (deuterium) atoms with ozone (O3). Sidelight spectroscopy was employed to verify the presence of chemi-excited OH and to estimate the concentrations of OH in various excited vibrational states. The existence of a partial inversion on the vibration-rotation levels of OH in its electronic ground state was established. The results were rationalized in terms of a simple kinetic model in which the hydrogen atoms are the limiting reagent. Using the data obtained in this program, the improvements in technology required to achieve lasing from OD in a device of pratical size have been identified, and specific recommendations for obtaining these improvements have been put forward.
