| 摘 要： | 通过分析六氟化硫气体在静态高电压和脉冲高电压作用下的绝缘特性对Marx模块式开关结构和外筒尺寸进行了优化设计，着重优化设计了Marx发生器中的两个关键绝缘部位——开关腔体结构和外金属筒与顶部电容绝缘距离，并通过数值模拟计算，分析了该区域的局部3维电场强度分布。结果表明:最大场强均小于六氟化硫的沿面闪络和电击穿场强阈值。对模块式开关腔和外筒尺寸进行优化得到的绝缘结构满足0.3 MPa下六氟化硫的绝缘要求。

| Abstract: | Based on the requirement and the influence of environmental factor on weapon system, two typical high energy fiber laser systems, coherent- and incoherent-combining types, were analyzed and compared. Beam propagation factor(BPF) was introduced as the beam quality factor for the combined beam. The influence of array element beam quality, atmospheric propagation, tracking jitter, phase control on the combined beam quality was numerically evaluated. The development trends of high energy fiber laser system were briefly discussed. |
