Title: High-pulse-repetition-rate HF laser with plate electrodes

Abstract

A high-pulse-repetition-rate electric-discharge HF laser with inductive-capacitive discharge stabilisation in the active H{sub 2}-SF{sub 6}-He mixture is studied. The multisectional discharge gap with a total length of 250 mm is formed by pairs of anode-cathode plates arranged in a zigzag pattern. The width of the discharge gap between each pair of plates is {approx}1 mm and its height is {approx}12 mm. The laser-beam cross section at the output cavity mirror is {approx}9 mm x 11 mm. The maximum laser pulse energy and the maximum laser efficiency for the H{sub 2}-SF{sub 6} mixture are 14.3 mJ and 2.1%, respectively. The addition of He to the mixture reduced the laser pulse energy by 10%-15%. The maximum gas velocity in the gap between the electrodes achieves 20 m s{sup -1}. The limiting pulse repetition rate f{sub lim} for which a decrease in the laser pulse energy is still not observed is {approx}2kHz for the H{sub 2}-SF{sub 6} mixture and {approx}2.4kHz for the H{sub 2}-SF{sub 6}-He mixture. The average output power {approx}27 W is obtained for a pulse repetition rate of 2.4 kHz. (lasers)
