[期刊论文] 作者:YanLi,HongbingJiang,HongYang,QihuangGong, 来源:ChineseOpticsLetters 年份:2005
Micro-optic elements have been fabricated in silica and soda-lime glass with femtosecond laser pulses. The dependence of refractive index change on pulse duration, pulse energy and scan passes is investigated and a Fresnel zone plate is ind......
