Paper Abstract

A simple corona phototriggered discharge has been operated in SF6/C2H6/Ne mixture at typical pressures 90-110 Torr, deposited energies up to 180 J/l and has resulted in the production of high energy HF laser pulse aroung 2.8 ?m. The maximum laser energy was 3.8 J per pulse which corresponds to a specific energy of 7 J/liter and to an efficiency of 4 % based upon the energy stored on the sustaining capacitor. Results of discharge modeling have shown that F atoms were mainly produced by electron excitation of SF6 dissociative electronic states.
