DARPA-NRL Laser Program - Semiannual Technical Report to Defense Advanced Research Projects Agency - 1 October 1976 - 30 March 1977

Abstract

The DARPA-NRL Laser Program is concerned with the development of laser technology of electronic state lasers and associated physics. In particular the development of the XeF laser has been emphasized. Experimental and theoretical efforts were made to understand and improve laser performance. The radiative lifetime of XeF was measured by photolytic dissociation of XeF2. A short pulse electron beam device was set up to remeasure the XeF lifetime more accurately and work was started to synthesize KrF2 in order to measure the lifetime of KrF. Values for the radiative lifetime are used in a code to predict laser performance of both XeF and KrF. Experimentally the performance of the XeF laser has been improved. Long laser pulses were observed for the first time and laser efficiency was increased by substitution of Ne for Ar, the diluent. Absorption measurements combined with code calculations showed that the improvement was due to decreased dimer ion optical absorption.
