Abstract:

The primary goal of this contract is to pursue research studies of tunable optical sources, to develop coherent sources in new spectral regions, and to conceive and to investigate new nonlinear optical devices of interest to the Air Force. During this contract our efforts have been concentrated on two primary projects experimental studies of possible metal vapor excimer laser systems, and a unique cesium vapor infrared to visible frequency converter for imaging. Early in this program a number of metal vapor excimer laser systems were investigated experimentally with the hope of demonstrating net optical gain. Based on a number of factors, it was hoped that such excimer systems might prove useful as high efficiency, high power density amplifiers or lasers in the visible or near infrared portion of the spectrum. Because of the lack of detailed knowledge of the interatomic potential of such systems, our investigaton was primarily experimental. Na-Ze, Li-Xe, and Na-Na systems were studied, but no net gain was observed in any case. In addition, these experiments revealed a number of severe technical problems related to the construction of high temperature, high pressure cells containing reactive metals.
