| Abstract: | A new approach for improving the efficiency of a copper bromide vapour laser with wavelengths of 510.6 and 578.2 nm is implemented. Multi-factor and regression analyses of a large amount of experimental data have outlined the parameters with highest impact on the laser efficiency. They are electric input power, inside diameter of the rings, distance between the electrodes, inside diameter of the laser tube, hydrogen pressure and electric input power per unit length.The results obtained allow discovery of the internal structure of dependences among parameters, to better account for the physical processes that influence efficiency, to improve the planning of further experiments and laser production technology. |
