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 lifetimes of XeF and KrF were measured by the photolytic dissociation of XeF/sub 2/ and KrF/sub 2/ respectively. In addition quenching rate constants and radiative lifetimes are used in a code to predict laser performance of both XeF and KrF. A description of the code is given. Experimentally efforts have been made to measure optical absorption in the XeF laser and to improve performance by investigating the role of the diluent gas. In other work, an excited metal-rare gas mixture was investigated to evaluate them as laser candidates. Finally quenching measurements of Ba were begun. If high values are obtained for the quenching measurements, there is a possibility that a Ba-N/sub 2/O electronic state chemical laser can be made.
