Abstract

In this work a copper chloride laser has been constructed and the effects of different parameters such as CuCl vapor pressure, buffer gas pressure, voltage and frequency on the output power and the ratio of green to yellow power at different buffer gas pressure have been measured. Thus, by optimization of these parameters and by the exact control of the copper chloride vapor pressure, as a result of increasing the distance between discharge and the lasant, a maximum specific output power of 123 (watt/lit) has been achieved. Based on the previous references, the reported specific output power in this work is the highest one among all of the copper halide lasers that have been constructed up to now, where the system is operating without any additives, like hydrogen.
