Abstract
A 20-kW fast-axial-flow CO2 laser has been realized by using high-frequency turboblowers developed especially for laser operation. Each of the two high-frequency turboblowers utilized in the equipment has a revolution of 8,800 rpm, a gas flow rate of 8.4 m3/s, and an adiabatic head of 4,000 kgf·m/kg. The equipment has six discharge-tubes connected optically in series, and each is 134 mm in diameter, and 1,000 mm in length. Stable glow discharge is established in the large-volume region without any preionization. The laser output power of 20 kW is extracted from an unstable resonator. The output beam through a zinc-selenide window has a diameter of 90 mn.
