摘要

本文描述了纳秒激光脉冲熔化材料在固体表面形成纳米结构的模型。结合成核理论，求解了具有相应边界条件的Stefan问题。研究发现，激光脉冲的能量和持续时间决定了表面纳米结构的典型尺寸。为了比较理论和实验结果，本文给出了各种工业材料(锗、钛、二氧化锆)经arf激光辐照后的结果。

Nanostructure Formation on Solid Surfaces melted by Laser Pulse

The paper describes the model of nanostructureformation on solid surface by nanosecond laserpulses melting the material. Stefan problem withcorresponding boundary conditions is solved incombination with nucleation theory. It is found thattypical size of surface nanostructure formeddepends on energy and duration of laser pulse. Forcomparison of theoretic and experimental resultsvarious industry material (germanium, titanium,zirconia dioxide) pieces irradiated by ArF-laser areshown.
