Optimization and elimination of black center of a large-bore copper vapor laser

• 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.
