Nano-Processing of Transparent Materials by Focussed Femtosecond Laser Pulses for the Development of Novel Bio-Microchip
Femtosecond laser Silica glass Chemical etching
2009/6/8
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...
Processing of Biomedical Tissue Materials by Femtosecond Laser Pulse
Femtosecond laser Hydroxyapatite Laser ablation
2009/6/8
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...
Single Cell Manipulation Using Femtosecond Laser Induced Shockwave
Femtosecond laser Micro processing Laser induced shockwave
2009/6/8
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...
Red and Green Distributed-Feedback LiF Color Center Lasers Fabricated by Interference of Femtosecond Laser Pulses
Color centers Distributed-feedback laser Femtosecond laser
2009/6/1
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...
Nano-aquarium Fabrication by Femtosecond Laser Direct Writing for Microscopic Observation of Aquatic Microorganisms
Nano-aquarium Femtosecond laser Photostructurable glass
2009/6/1
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...
Quenching of High-Pressure Phases of Silicon Using Femtosecond Laser-driven Shock Wave
Femtosecond laser Silicon Shock wave
2009/6/1
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 Utilizing Plasmon on Glass Surface by Femtosecond Laser Pulse with Template of Dielectric Particle Array
Femtosecond laser Nano-processing Nano-particle
2009/6/1
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 ...
Nanostructuring Process in Femtosecond Laser Ablation of Patterned Thin Film Surfaces
Femtosecond laser ablation Nanostructuring Local field Patterned substrate
2009/6/1
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...
Three-dimensional Femtosecond Laser Integration in Glasses
Femtosecond laser microfabrication Three-dimensional integration Glass chips
2009/6/1
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...
Processing microstructure on film by femtosecond laser
femtosecond laser Au/Cr film process
2009/3/10
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 ...
