Performance of CuII lasers with cylindrical hollow cathodes
Abstract
The design of a Cu II laser having cylindrical hollow cathodes with different bore diameters is described. The performance of this device in the IR mode of operation with discharges in He:Ar mixtures is evaluated experimentally. It is found that losses can be minimized, and discharge stability increased, by using a small anode-cathode gap and proper water cooling. The laser parameters are shown to have a strong dependence on cathode geometry. The experimental results indicate that short cathodes with a length of 20 mm and a bore diameter of 7 mm give the highest laser output and efficiency.
