We report fabrication of three-dimensional (3-D) microchannels inside transparent materials. The 3-D microfabrication was achieved by two steps. First, femtosecond pulses were focussed into the transp...
The micromachining of hydroxyapatite (HAp) and collagen is highly required for orthopedics and dentistry, because human bone and tooth consist mainly of HAp oriented along the collagen. We have evalua...
A shockwave induced by focusing an intense femtosecond laser on a culture medium under a microscope was applied to manipulate single bio-cell. Propagation dynamics of the shockwave was investigated by...
Sub-micron periodic gratings inside bulk lithium fluoride (LiF) are holographically fabricated by interference with the second harmonic (390 nm) of a mode-locked Ti:sapphire oscillator-amplifier laser...
We demonstrate the fabrication of three-dimensional (3-D) hollow microstructures embedded in photostructurable glass by a femtosecond (fs) laser direct writing. Fs laser direct writing followed by ann...
High-pressure phases which are Β-Sn, Imma and simple hexagonal structures of silicon are quenched using an intense femtosecond laser-driven shock wave. These high-pressure phases have never synthesize...
Nano-processing using a near-field generated by laser irradiation onto the nano-particle is becoming a new emerging nanofabrication technology, because it can fabricate nano-sale structures even with ...
To study the physical mechanism of femtosecond (fs) laser induced nanostructuring on solid surfaces, we observed the initial stage of morphological change on diamond-like carbon and titanium nitride f...
In the past decade, femtosecond (fs) laser microfabrication has received significant attention because of its powerful three-dimensional (3D) integrating and manufacturing capabilities. A series of mu...
Selective laser patterning of thin films in a multilayer film is an emerging technology for fabrication of MEMS devices. A 775 nm Ti:sapphire laser (130 fs, 1 kHZ) was used to irradiate the thin film ...

期刊信息 篇名 Vacuum heating of solid target irradiated by femtosecond laser pulses 语种 英文 撰写或编译 作者 董全力,张杰 第一作者单位 刊物名称 《中国科学》(G辑) 页面 46(1),625-631(2003) 出版日期 2003年 月 日 文章标识(ISSN) 相关项目 对超热电子在高密度等离子体中传输的研究
We present a new method to investigate the ablation phenomenon by a 100 fs, 1053 nm Gaussian laser pulse in fused silica and describe the different mechanisms of ablation in long pulse and ultrashort ...
