英文摘要	Three types of surface nanostructures are fabricated on tungsten by adjusting azimuth angle. of YVO4 birefringent crystal and laser parameters in experiment. Different surface structure morphologies are introduced and their features are investigated. The frequency characteristics of the three type laser-induced surface nanostructures are studied by the fast Fourier transformation (FFT). By varying the azimuth angle of YVO4 crystal we can not only convert one-dimensional (1D) grating-like structures into two-dimensional (2D) surface structures, but also control the structural arrangement. Compared with traditional two-step sequential processing method, the dual orthogonal pulses generating through YVO4 birefringent crystal can induce better periodical 1D grating-like structure. Moreover, the 2D microbumps are mainly dependent on the energy deposition effect from dual pulses. We also provide the underlying texturing mechanism of final periodic surface structures.
