Applying a genetic algorithm and taking the maximum output as an objective funct ion, a copper vapor laser with about 100W output is optimized and designed for reducing the “black center” of the radial laser intensity. The “black center ”, which results from the skin effect of the continuing pulsed field, is reduce d and the output is increased significantly by optimizing the laser tube radius- length and the LC circuit parameters.
