摘要：

Two-dimensional 'hat-scratch' structures are fabricated on silica glass by the interference of three non-coplanar beams originating from a single femtosecond laser pulse. The scanning electron microscope (SEM) characterizations show that the as-formed structures are composed of hat holes and scratch marks. The experimental results indicate that the structures are dependent on the intensity of laser beam. The formation of the two-dimensional 'hat-scratch' structures is mainly due to the combined laser ablation effects including ionization, shock wave, plasma expansion, and phase explosion.
