Relative influence of hydrogen/deuterium donors and driving circuit parameters on the performance of a uv preionized pulsed HF/DF laser
The influence of the preionizer and initiating discharge circuit parameters on the performance of a UV preionized pulsed HF/DF chemical laser with relatively low active volume (about 20 cm/sup 3/) has been investigated. The laser has been operated with gas mixtures of SF/sub 6/ and H/sub 2/, C/sub 2/H/sub 6/, and D/sub 2/ at pressures < or =90 Torr, giving laser output energies up to approx.70 mJ with a maximum efficiency of about 2.2%. We observed that the insertion of a peaking capacitor bank across the main discharge gap strongly affected the laser output characteristics. The laser output energy was seen to vary with the capacitance of the peaking capacitor bank, whose influence is a function of the SF/sub 6/ partner in the laser mixture, the gas pressure, and the input energy density into the discharge.
