Abstract

Initial performance of an electric-discharge initiated HF/DF chain reaction laser is presented. The discharge is triggered by a short X-ray pulse while a voltage just under the breakdown voltage is applied accross the electrodes. Information is presented on the effects of several parameters on laser performance. Using a 6 F2/2 H2/1 02/91 Ne gas mixture, laser energies up to 13 J/1 were obtained at a pressure of 0.7 bar. This corresponds to an electrical efficiency of 15 % and a chemical efficiency of 4.5 % based on the H2 content.
