Paper Abstract

The experimental study of a repetitively pulsed chemical HF laser operating on a chain reaction F2 +H2, initiated by the barrier electrical discharge with the inter-electrode gap 10 cm, with length of active medium 40 cm along optical axis has been carried out. The barrier electrical discharge with duration about 120 ns has shown a high stability, reliability and homogeneity at specific energy deposits up to 60 J / 1. At the repetition pulses rate 10 Hz with the depleted fluorine-hydrogen mixture (20 % F2, 5 % H2), the mean laser power 500 W (a specific energy for one laser pulse E/V ≈ 11.6 J / 1, technical efficiency of 15.6 %) is achieved. In the single pulse mode of the laser operation with the mixture 30 % F2, 12 % H2 the maximum pulse energy Emax = 100 J, the specific radiation energy E/V = 24 J / 1, the technical efficiency &hookn;tech = 28.4 % are obtained.
