Abstract
A gain generator 10 for use in high-energy flowing gas lasers such as COIL devices comprises a chemical reactant mixing nozzle 12 disposed in a gain medium 16. The nozzle includes a plurality of blades 22 formed of a plastic material resistant to chemical attack at the operating temperature of the gain medium and non-catalytic to O.sub.2 (.sup.1 .DELTA.). A preferred material is polyetherimide. The gain medium includes octagonal shaped openings 50 for the optical mode of the laser beam.
