Abstract

A linear to radial and/or azimuthal polarization converter (LRAC) has been inserted into the beam delivery of a micromachining station equipped with a picosecond laser system. Percussion drilling and helical drilling in steel have been performed using radially as well as azimuthally polarized infrared radiation at 1030 nm. The presented machining results are discussed on the basis of numerical simulations of the polarization-dependent beam propagation inside the fabricated capillaries.

摘要

一个线性到径向和/或方位角偏振转换器（LRAC）已被插入到配备皮秒激光系统的微加工站的光束传输路径中。利用1030nm的径向以及方位角偏振红外辐射对钢进行了冲击钻孔和螺旋钻孔。基于所制造毛细管内偏振相关光束传播的数值模拟，对所呈现的加工结果进行了讨论。
