研制了一种用于高性能钻孔的方位偏振脉冲周期CO2激光器。我们发现，与径向或随机偏振光束相比，方位角偏振光束的钻速异常增强。我们使用焦距为50 mm、数值孔径（NA）为0.09的聚焦透镜钻了0.45 mm厚的碳纤维增强塑料（CFRP）。除偏振态外，所有实验的条件均相同。方位角偏振光束的钻速平均比其他两种偏振光束的钻速大10倍以上。
We developed an azimuthally polarized pulse-periodic CO 2 laser for high-performance drilling applications. We discovered an anomalous enhancement in the drilling rate with the azimuthally polarized beam compared to that with radially or randomly polarized beams. We drilled 0.45 mm-thick carbon fiber reinforced plastic (CFRP) using a focusing lens with a focal length of 50 mm and a numerical aperture (NA) of 0.09. The conditions other than polarization states were identical for all the experiments. The azimuthally polarized beam exhibited a drilling rate more than 10 times greater on average than those of the other two polarizations.
