[16p-A201-7] Laser Ablation by Tightly Focused Vector Beams

〇Yuichi Kozawa¹, Yukine Tsuru¹, Yuuki Uesugi¹, Shunichi Sato¹ (1.IMRAM, Tohoku Univ.)

Keywords:Vector beam, Laser ablation, Longitudinal field

We present our experimental results regarding the laser processing application using vector beams including radially polarized beams that have unique focusing properties under tight focusing conditions. The contribution of the focusing property to the laser ablation process and its potential applicability to finer laser micro-processing are discussed.
