Description
Summary:An electric-discharge XeCl minilaser and the results of its experimental modeling are described. The laser uses a two-stage system of magnetic compression of current pulses, semiconductor high-voltage bipolar transistors as a switch, and preionization of the working medium by barrier discharge radiation from under the grid electrode. The dependence of the output parameters of the minilaser on the excitation conditions and the composition of the active medium is derived. The maximal pulse energy of ∼12 mJ was obtained for a mixture 1.5 Torr HCl + 15 Torr Xe + 4 atm Ne at a voltage across the peaking capacitor of 20 kV and a lasing pulse duration at half maximum of ∼20 ns. The efficiency of the XeCl minilaser in terms of the energy stored in the sharpening capacitor is ∼4%.
