Paper Abstract

A quantitative study of beam extra amplification is conducted for carbon-dioxide lasers with fast axial turbulized gas flow. In this phenomenon, the dominant role is played by turbulent diffusion of excited molecules into the central saturation part of the beam. It has been shown that the decrease in beam radius causing the reduction of diffraction losses allows us to attain greater amplification owing to turbulent diffusion, and it is supported by experiment.
