Journal ArticleDOI
Selective appearance of several laser-induced periodic surface structure patterns on a metal surface using structural colors produced by femtosecond laser pulses
Jian-Wu Yao,Chengyun Zhang,Hai-Ying Liu,Qiao-Feng Dai,Lijun Wu,Sheng Lan,Achanta Venu Gopal,Vyacheslav A. Trofimov,Tatiana M. Lysak +8 more
TL;DR: In this article, the authors used femtosecond laser pulses to induce ripples with a subwavelength period on the surface of a stainless steel (301 L) foil, which can be used to decorate different regions of the surface with different types of ripples.
Journal ArticleDOI
Lighting up silicon nanoparticles with Mie resonances.
Chengyun Zhang,Chengyun Zhang,Yi Xu,Jin Liu,Juntao Li,Jin Xiang,Hui Li,Jinxiang Li,Qiao-Feng Dai,Sheng Lan,Andrey E. Miroshnichenko +10 more
TL;DR: The Mie resonances in silicon nanoparticles are utilized to demonstrate visible white-light emission, both from free-standing spheres and particles etched on a silicon-on-insulator substrate.
Journal ArticleDOI
High spatial frequency periodic structures induced on metal surface by femtosecond laser pulses
Jian-Wu Yao,Chengyun Zhang,Hai-Ying Liu,Qiao-Feng Dai,Lijun Wu,Sheng Lan,Achanta Venu Gopal,Vyacheslav A. Trofimov,Tatiana M. Lysak +8 more
TL;DR: The high spatial frequency periodic structures induced on metal surface by femtosecond laser pulses was investigated experimentally and numerically and the proposed formation process is supported by both the numerical simulations based on the finite-difference time-domain technique and the experimental results obtained on some metals such as stainless steel and nickel.
Journal ArticleDOI
Formation of 100-nm periodic structures on a titanium surface by exploiting the oxidation and third harmonic generation induced by femtosecond laser pulses
TL;DR: It was revealed that an extremely thin TixOy layer was formed on the surface of the Ti foil after irradiating fs laser light with a fluence smaller than the ablation threshold of Ti, leading to a significant enhancement in THG which may exceed the ablated threshold of TIXOy.
Journal ArticleDOI
Colorizing silicon surface with regular nanohole arrays induced by femtosecond laser pulses.
Chengyun Zhang,Jian-Wu Yao,Hai-Ying Liu,Qiao-Feng Dai,Lijun Wu,Sheng Lan,Vyacheslav A. Trofimov,Tatiana M. Lysak +7 more
TL;DR: It is found that the length and depth of the initially formed gratings plays a crucial role in the generation of 1D or 2D nanohole arrays.
