Assessment of the maximum supplied electric power for a pure copper vapor laser

Based on a previously proposed model for analytical calculation of gas temperature, an improved methodology for determining the threshold of the supplied electric power in the active laser volume is developed. A comparison is made with previous publications. It is noted that the proposed methodology is better at accounting for the processes of heating and cooling of the laser tube. It is shown that the proposed methodology can be applied to a wider range of metal vapor lasers and other high-voltage devices, operating at high temperatures.
