Having each thread generate it's own beam would duplicate the input data so I'd like to avoid that (also, the it's much more efficient to generate multiple beams at one go).

每个线程生成它的光束将重复的输入数据，我想避免(同样，是更有效的生成多个光束在一次)。

In the process of duplicate laser boring, the crosswise pattern of laser beam determines the precision of the processing hole's shape and size.

在复制法激光打孔中，激光束的横向模式决定着加工孔的形状和尺寸精度。

In a process similar to printing a photograph, engineers beam high-powered light through a masklike image of the chip, thus creating a duplicate on a silicon wafer.
