摘要

利用偏振光奇异束变换器[1]合成了双电荷飞秒涡旋。采用中高数值孔径光学(NA = 0.45和0.9)聚焦涡流，烧蚀熔融石英和钠钙玻璃。结果表明，烧蚀可以控制在亚微米尺度上，具有很高的重复性。

Focused femtosecond vortex laser pulse

Double-charge femtosecond vortices were synthesized with the polarization-singularity beam converter [1]. The vortex was focused using moderate and high numerical aperture optics (NA = 0.45 and 0.9) to ablate fused silica and soda-lime glasses. The results demonstrate that the ablation can be controlled on a sub-micrometer scale with a high degree of repeatability.
