Abstract

The paper presents the experimental results on how the tube bore of copper bromide laser influence the gain radial distribution. A pair of copper bromide lasers in an oscillator- amplifier configuration was operated to measure and compare the small-signal gains of different laser tube bores. The gain radial distributions were measured in different size of amplifier tube bores. It was shown that, by changing of the amplifier tube bore, the gain radial distribution was changed, similar to that of temperature profile, but the average of radial gains through cross-section are the same in different laser tube bores.
