摘要	The studies of a repetitively pulsed deuterium fluoride (DF) laser based on electric-discharge and closed cycle are presented. Using double-pressure tank circuit and a rough cathode, the self-sustained volume discharge of 1.65 L is obtained in SF6-D2 mixtures. A centrifugal fan provides adequate gas flow to refresh mixture gas quickly. The gases pass through a scrubber cell in which ground state DF molecules are eliminated from the gas stream. The influences of gas parameters and charging voltages on the output characteristics of non-chain pulsed DF laser are investigated experimentally. At the charging voltage of 43 kV, under the optimum working condition (the working gas ratio is 8:1, the total pressure is 8.1 kPa), a maximum output energy of 3.46 J, an electro-optical conversion efficiency of 3.12% and a pulsed width of 135 ns are got. At an operating repetition rate of 50 Hz, a maximum average output power of 150 W is obtained, whose amplitude difference of laser pulses is less than 8%. The far-field divergence angles in horizontal and vertical directions are 7.92 mrad and 9.58 mrad, respectively. 22 P-branch transition lines are achieved using DF laser spectrum analyzer. The result show that the pulsed electric-discharge DF laser is an effective technology to obtain high power mid-infrared laser. , 2015, Science Press. All right reserved.
