Abstract

An electric-discharge XeF-laser with a pulse repetition rate up to 4 kHz was developed. The laser electrode unit was made on the basis of plate-like electrodes with inductive-capacity discharge stabilization. The narrow discharge width ≤ 1 mm was realized. The buffer gases He and Ne with NF₃ as the donor of fluorine were used. The specific pump energy per unit length of the active volume was 2 J/m. The maximum laser energy was 3 mJ by using He/Xe/NF₃ and Ne/Xe/NF₃ mixtures at the total pressure of 0.8 atm and 1.2 atm, respectively. The maximum laser efficiency was ≈ 0.73% The gas flow was formed with the help of a diametrical fan rotated by the direct-current motor with 80 W power. The gas velocity of 20 m/s in the interelectrode gap was achieved. The laser pulse energy for a pulse repetition rate up to 3.5...4 kHz was virtually equal to the laser pulse energy in the infrequently-repeating-pulse regime. The average output power of 12 W at the pulse repetition rate of 4 kHz was achieved. The relative root-mean-square pulse-to-pulse variation of the output energy σ = 2.5% was reached.
