[期刊论文] 作者：ZhiLuo,CongWang,XinranDong,Ji’anDuan,
来源：ChineseOpticsLetters 年份：2018
A simple technique is proposed for highly-efficient plane processing fully based on femtosecond laser beam shaping. The laser intensity distribution is transformed from a Gaussian to a donut shape. As the donut-shaped focus seems like a fla......
Ablation enhancement by defocused irradiation assisted femtosecond laser fabrication of stainless al

We evaluate the effects of the holes geometry drilled by a femtosecond laser on a stainless alloy with various defocused irradiation time, which ranges from 0 min to 1 h. The laser ablation efficiency is increased by a factor of 3 when the ......

Resonant effect is found in femtosecond laser ablating Pr–Nd glass. When processed with resonant wavelength of 807 nm, resonant ablation efficiency (RAE) with a single pulse can be improved by 45.22%. Furthermore, RAE closely relates to la......
Controllable annulus micro-/nanostructures on copper fabricated by femtosecond laser with spatial do

In this study, we propose an effective method for the fabrication of annulus micro-/nanostructures by a femtosecond laser doughnut beam. Compared with the traditional Bessel annulus beam shaping system, this method greatly compresses the li......
Micro-channel etching characteristics enhancement by femtosecond laser processing high-temperature l

A fused silica glass micro-channel can be formed by chemical etching after femtosecond laser irradiation, and the successful etching probability is only 48%. In order to improve the micro-channel fabrication success probability, the method ......
