Abstract

The design of a large-bore copper vapor laser amplifier (CVA) intended for the application to high-power laser systems operating in the 'master oscillator ('MO-amplifier') mode is described. The discharge volume of the amplifier laser head is 70 mm in diameter and about 2000 mm in length. The results of experimental studies of the CVA operating in the lasing mode at a pulse repetition rate of 4 - 6 kHz and a buffer gas pressure of 30 - 80 Torr are presented in the paper. Stable operation of the CVA was achieved at an output power of 100 +/- 5 W and approximately 1% efficiency.
