摘要
利用近红外飞秒激光脉冲对玻璃和聚合物等透明凝聚态物质进行微纳制备.通过飞秒激光诱导的折射率变化在石英玻璃内部制备光栅等折射率型元器件;从后表面开始钻孔并引入蒸馏水,在钠钙玻璃中加工出纵横比很大的微细直孔;改变飞秒双光子聚合中激光焦点在样品中的位置,聚合出直线型和波浪型等不同形状的线条.
Abstract
Near infrared femtosecond laser micro/nano-fabrication using in transparent condensed matters like glass and polymers was reported. Femtosecond laser induced refractive index change was used for fabrication of gratings and other elements inside silica glass. Drilling from rear surface in contact with water, microholes with large aspect ratio were machined in soda-lime glass; With the change of laser focus inside two-photon absorption polymer, straight and wavy lines are polymerized.
