Discharge characteristics and laser performance of non-chain HF laser

The experimental setup and performance of a non-chain transverse excited HF laser with UV pre-ionization is described. Electric discharge characteristics in gas mixture of SF6 /C2H6 are investigated for various initial conditions by recording the discharge plasma fluorescence intensity and temporal evolution of discharge current and voltage. The laser pulse energy is studied in different charging voltage, gas mixture pressure and concentration. It is shown that the process of discharge in gas mixture has three phases: glow discharge, voltage plateau and arc discharge. The optimal energy deposition obtained at the critical point that the voltage plateau just disappears. Maximal output energy of 0.6J and electrical efficiency of 2.5% are obtained.
