摘　　要：在卤化铜激光器脉冲放电电源系统中 ,为减轻闸流管的工作负担并同时保证电路的快放电激励 ,采用了单级磁脉冲压缩器 .分析了磁脉冲压缩器的工作机理 。In copper halide lasers, the excitation of copper atoms is produced through the discharge of a storage capacitor. Performances of it were essentially linked to the type of switch used and also to its mode of operation. Thyratrons are the most common switches. Nevertheless, their technological limitations do not allow a high repetition rate and high rate of rise of current. But these limitations can be surpassed by combining the thyratron to magnetic pulse compression (MPC). The MPC driver can improve the laser excitation pulse rise time and increase the repetition rate. A single stage MPC system for CuBr laser has been developed in this paper. With this MPC, the power of laser output was increased more than 20%. The mechanism of MPC performance was analyzed. The design advisements and parameter choices of MPC were presented particularly.
