Paper Abstract

Results of the investigation of the discharge parameters, active medium homogeneity and stability, and laser performance are reported for a 2.5x2.5x50 cm3 HF phototriggered laser working either in chain and non-chain mode. Using a Ne/F2/H2/O2=93/5/1.5/0.5 mixture, a specific output laser energy of 9 J/l was obtained with an electrical efficiency of 38%. Compared to the performance ofnon-chain reaction HF lasers, these data correspond to an increase ofthe efficiency by a factor of 8. However, due to the development of discharge instabilities the output laser energy is not higher than that obtained with the non-chain laser mixtures.
