Abstract

We fabricate Au microneedle structures by irradiating nanosecond optical vortex pulse, possessing orbital angular momentum (OAM), to Au thin film. Twisted microneedle associated with the handedness of optical vortex is formed. The partial liquid motion of the molten Au film and the OAM transfer effects play a role to establish a twisted Au microneedle. An Au microsphere on a twisted pillar is also achieved. Non-twisted structure is fabricated with picosecond optical vortex pulse irradiation due to unoptimized condition such as laser fluence, film thickness and unavoidable imperfections of the optical vortex.

利用光学涡旋光束微细加工金薄膜

利用具有轨道角动量(OAM)的纳秒级光涡旋脉冲照射金薄膜，制备了金微针结构。形成了旋光涡旋旋向的旋光微针。熔融金膜的部分液体运动和OAM传递效应是形成扭曲金微针的主要原因。在扭曲柱上也实现了一个金微球。由于激光通量、膜厚等非优化条件和光涡旋不可避免的缺陷，采用皮秒光涡旋脉冲辐照制备非扭曲结构。
