Abstract

A titanium surface has been irradiated by a femtosecond laser in n-hexane at different pressures. The influence of laser-induced plasma on the character of formation of the surface-periodic structures in the pressure range from 6 mbar to 22 bar has been considered. The surface of the treated samples is analyzed by scanning electron microscopy. It is shown that the period of the obtained laser-induced ripple structures depends on pressure in the working vessel and the treatment mode.

正己烷中不同压力下钛表面激光诱导的空间周期性结构

摘要

飞秒激光在正己烷中以不同的压力照射了钛表面。已经考虑了在6 mbar至22 bar的压力范围内，激光诱导的等离子体对表面周期结构形成特性的影响。通过扫描电子显微镜分析处理过的样品的表面。结果表明，获得的激光诱导波纹结构的周期取决于工作容器中的压力和治疗方式。
