Tight focusing of a radially polarized beam is used for single-shot laser ablation of metals. The strong longitudinal field is generated at the focus, and its contribution to the ablation process is comprehensively examined for various metal materials. In the presence of the longitudinal field at the focus, a fabricated crater at the surface exhibits either a spot shape or a doughnut shape, depending on the material. The experimental results indicate that the strong longitudinal electric field on metal surfaces is capable of promoting
