Abstract

The pulsed barrier discharge for molecular (CO₂) laser excitation is presented and its superior characteristics are discussed. The volume-uniform barrier discharge in nitrogen and N₂:CO₂He mixture at 500 hPa is confirmed for nanosecond pulse generator. The spatially homogeneous discharge in whole working-gas volume, which is of key-importance for laser technology, was generated. In all considered cases the values of maximal energy deposition for pulse generator exceed 50-100% these obtained using AC sinus-like power-source. Moreover, the electrical efficiency of a pulsed generator was close to that of AC power-supply.
