Paper Abstract

Alumina plates (Gas-cooling plates) were inserted into the plasma tube of copper vapor lasers to cool the buffer gas at the center of the plasma tube. Consequently, the laser intensity increased, especially at the center, and higher output power was obtained. It was revealed by measurement that the gas-cooling plates reduce the buffer gas temperature and the lower laser level density of copper atoms at the center of the plasma tube. Output characteristics were measured by varying the repetition frequency. Plate insertion improved the central intensity at higher frequencies. Output power was most dependent on the frequency with the plate inserted, and increased proportionally as the frequency increased.
