Abstract

The working mechanism of the non-chain pulsed DF laser is analyzed in this paper, then the glow discharge with the method of UV-preionized discharge is displayed, and finally the experimental investigation on the output characteristics of non-chain pulsed DF laser is done. With SF₆, which is non-toxic and non-corrosive, and D₂ as the active medium, the dependence of the output characteristics of pulsed DF laser on the gas mixture ratio and the total pressure are investigated. In the experiment, the optimal gas mixture ratio of SF₆-D₂ and total pressure are 10:1 and 10.5kPa, respectively. At the same time, by making a measurement on the output spectrum of DF laser with a DF laser spectrum analyzer, 17 P-branch transition lines are achieved and the majority of output energy is concentrated on several lines near the 3.876μm line. The laser beam divergence angles in horizontal and vertical directions are 1mrad by using the laser spot ablation method. At the charging voltage of 39kV, under the best working condition(SF₆: D₂ = 10:1, P_total= 10.5kPa), the maximum single pulse output energy of 3.58J, pulse duration of 215ns, peak power of 16.65 MW, and electro-optical conversion efficiency of 2.08%, are obtained.
