【 摘 要 】

The amplifier elements upgrade at the Luch laser facility was carried out. Measurements showed that the upgrade of the amplifier elements resulted in the amplifier's small signal gain coefficient K0increase from 12.9% to 14.3% depending on the capacitor charging voltage; the linear gain coefficient increase was about g0≈ (6-8)%. Full-scale laser experiments at the facility showed the power amplifier gain coefficient increase consistent with active medium gain coefficient measurement results.
