Intracavity absorber effects in a CW dye laser. Final report, June 1, 1977-December 31, 1981
The purpose of this work was to explore the suitability of dye laser intracavity absorption as a potential diagnostic techniques for use in combustion systems. In order to obtain a high resolution probe of the dye laser, atomic beams of sodium and barium were used as the absorbing medium. The resulting measurements led to the development of a new model for describing intracavity absorption which is able to account for all observed features of the phenomenen. It was shown in this work that intracavity absorption can also be observed in a plasma, and that in such an environment it is possible to observe absorption in excited atomic states whose lifetimes are of the order of 10/sup -8/ seconds. The general conclusion is that dye laser intracavity absorption should provide a useful diagnostic technique at least in laminar flames.
