用多次线偏振飞秒脉冲（130 fs, 800 nm）在空气中照射单晶磷化铟（c-InP）后，观察到具有不同空间特征的激光诱导周期表面结构（LIPSS；波纹）。随着每个光斑脉冲数的增加，N增加到100，观察到两种不同类型波纹的特征演变，即：(i)垂直于由近波长大小的周期线组成的偏振矢量的光栅的生长；（ii）在特定脉冲数范围内（N=5-30），空间周期接近激光波长一半的等取向波纹的额外形成。当脉冲数大于50时，发现形成微米间距的沟槽，其方向垂直于波纹。在现有的LIPSS理论框架中讨论了这些地形表面变化。(C) 2005美国物理研究所。
Laser-induced periodic surface structures (LIPSS; ripples) with different spatial characteristics have been observed after irradiation of single-crystalline indium phosphide (c-InP) with multiple linearly polarized femtosecond pulses (130 fs, 800 nm) in air. With an increasing number of pulses per spot, N, up to 100, a characteristic evolution of two different types of ripples has been observed, i.e., (i) the growth of a grating perpendicular to the polarization vector consisting of nearly wavelength-sized periodic lines and (ii), in a specific pulse number regime (N=5-30), the additional formation of equally oriented ripples with a spatial period close to half of the laser wavelength. For pulse numbers higher than 50, the formation of micrometer-spaced grooves has been found, which are oriented perpendicular to the ripples. These topographical surface alterations are discussed in the frame of existing LIPSS theories. (C) 2005 American Institute of Physics.
