HIGH POWERED DIFFRACTION LIMITED RAMAN LASER

Abstract

The problems associated with the production of diffraction-limited Raman based laser-like devices were investigated. The most persistent effort was directed at understanding several of the rather serious deviations between theory and experiment. The most noteworthy problem treated is the anomalous gain of Stimulated Raman Scattering (SRS). At present, it appears that the solution is contained in considering light trapping effects as the cause of a highly increased power density in the Raman material. Currently, efforts are continuing to explain the mechanism of the trapping as well as relating these effects to other problems in SRS.
