Paper Abstract

A comprehensive investigation of the main parameters that determine the effective power scaling of diffusion cooled annular CO2 lasers in the 3kW region is presented. Aspects such as RF excited discharge characteristics; small signal gain, free space resonator configuration, beam stability and quality are discussed in detail. Simulations of the resonator system are presented and different shapes for the azimuthal direction are evaluated for power and stability.
