Effects of Laser Scanning Conditions on Metallic Micro/Nanostructures in Multiphoton Nanofabrication

The influences of laser scanning conditions on the silver micro/nanostructures in multiphoton photoreduction of metallic micro/nanostructures and morphology using femtosecond laser were investigated.The results indicated that increasing the distance between scanning points(d) could make the width of lines become smaller and extending the exposure of time(t) could make the lines broadening.Furthermore,the increasing of scanning times(N) led to the formation of large silver particles and lumps on the structures due to the fusion of silver nanoparticles which on the surface of metallic micro/nanostructures.
