Thermal design of copper vapor laser

The design procedure of copper vapor laser is emphasize,in this paper.on the basis of large amount of expelment data,the selection principles of discharge tube size and input discharge perwer unit volume are presented.According to the gas temperature distribution in dischage tube and coaxi heat conductivity laal.The thicknes of alumina fiber can be determined.The phenomena called"black center of beam" is analyzed and the solvable metals is suggested.The design idea is verified verywell with a SW copper vapor laser developed by us recently.
