摘要： A beam sampling system, includes a first beam splitter adapted to split a laser beam having a primary polarization component and a secondary polarization component, into a first intermediate sample beam, and a first beam splitter output beam, the intermediate sample beam including first percentage of the primary polarization component and a second percentage of the secondary polarization component. A 90-degree polarization rotator is positioned in the intermediate sample beam line. A second beam splitter is mounted so that the intermediate sample beam is split into an output sample beam on an output sample beam line, and a second transmitted beam, the output sample beam including substantially said first percentage of the secondary polarization component and substantially said second percentage of the primary polarization component.

摘要翻译： 用于高功率激光系统（例如激光喷丸系统）的用于可能具有复合曲率的工件的光束传输技术包括将具有接收光学器件，光束格式化光学器件和安装在其上的扫描器的光学组件放置在接收激光脉冲的位置 来自激光源并且在过程区域的操作范围内。 当光学组件的位置保持不变时，偏振激光脉冲被传送到接收光学器件。 脉冲通过光束格式化光学器件前进到扫描器，并且直接到达在工件上具有标称形状和位置的相应冲击区域。 扫描过程包括对于每个激光脉冲，包括从扫描仪输出的激光脉冲的设置方向，发散度，偏振，旋转和宽高比，以控制相应碰撞区域上的偏振，形状和位置。
