KrF short pulse extraction studies
Abstract
A series of measurements on the KrF laser system was carried out using 200 ns fast rise time pulse at currents up to 50 A sq cm to approximate conditions of interest for the DOE inertial confinement fusion progress. These measurements include fluorescence efficiency, sidelight suppression of the fluorescence during lasing and laser energy output over a wide range of parameters including: 0.5 ama p 2.0 ama, 3000 K T 4500 K, 0.15% F2 0.5%, 40 A/sq cm I 50 A/sq cm and various output couplings. The KrF model was modified to match the results. These modifications include a simplified 2 upper level model to describe the vibrational relaxation and its effect on energy extraction.
