• A copper vapor laser (CVL) with 6 cm diameter and 300 cm discharge length has been developed for atomic vapor laser isotope separations. Recently, output power of over 200 W (211 W maximum) has been steadily obtained. The authors developed a thermal calculation code to maintain an optimum copper vapor density throughout a large volume and a discharge analyzing code to supply discharge energy efficiently into the laser tube. Connecting these codes to Kushner's CVL simulation method yields results which agree well with experimental results. And high-performance CVL could be designed by these codes which simulated the thermal and electrical characteristics of a CVL. In addition, a new thermal insulation structure design method has been proposed to combine two different heat insulators to make longitudinal temperature distribution of the laser tube as flat as possible. A CVL discharge circuit has been improved by applying an excellent magnetic assist which has been able to operate at high repetition rate (5 kHz)oscillating condition.<BR>This paper reports such CVL design methods together with the performance of the designed high-power CVL.
