How to Obtain Metal Surface with Ultralow Reflectivity?

Chinese Academy of Sciences To fabricate micro/nano structures on metal surfaces, various technologies have been proposed, including chemical etching, mechanical grooving, reactive ion etching, and long-pulse laser processing. Ultrafast laser manufacturing technology is one of the relatively ideal technologies for fabricating light-trapping structure surfaces. However, to simply and effectively achieve broadband effectiveness and ultralow average reflectivity performance on metal surfaces still remains challenging. A research team led by Prof. LIU Hongjun from Xi’an Institute of Optics and Precision Mechanics (XIOPM) of the Chinese Academy of Sciences (CAS) proposed an effective and simple method for fabricating the micro/nano hybrid structures on metal surfaces by adjusting femtosecond laser fluence, scanning interval, and polarization.
