Journal ArticleDOI
Femtosecond laser-assisted three-dimensional microfabrication in silica.
Andrius Marcinkevicius,Saulius Juodkazis,Mitsuru Watanabe,Masafumi Miwa,Shigeki Matsuo,Hiroaki Misawa,Junji Nishii +6 more
TL;DR: This technique allows fabrication of 3-D channels as small as 10mum in diameter inside the volume with any angle of interconnection and a high aspect ratio.
Journal ArticleDOI
Three-dimensional photonic crystal structures achieved with two-photon-absorption photopolymerization of resin
TL;DR: In this article, three-dimensional photonic crystal structures were fabricated with laser microfabrication techniques through two-photon-absorption photopolymerization of resin, and significant band-gap effects in the infrared wavelength region were observed from layer-by-layer structures.
Journal ArticleDOI
Plasmon-Assisted Photocurrent Generation from Visible to Near-Infrared Wavelength Using a Au-Nanorods/TiO2 Electrode
TL;DR: In this article, the plasmonic photoelectric conversion from visible to near-infrared wavelength without deteriorating photo-electric conversion by using electrodes in which gold nanorods are elaborately arrayed on the surface of a TiO2 single crystal.
Journal ArticleDOI
Laser-induced microexplosion confined in the bulk of a sapphire crystal: evidence of multimegabar pressures
Saulius Juodkazis,Kouichi Nishimura,Satoru Tanaka,Hiroaki Misawa,Eugene G Gamaly,Barry Luther-Davies,L. Hallo,Ph. Nicolaï,Vladimir Tikhonchuk +8 more
TL;DR: Analysis of the size of the void and the shock-affected zone versus the deposited energy shows that the experimental results can be understood on the basis of conservation laws and be modeled by plasma hydrodynamics.
Journal ArticleDOI
Laser-matter interaction in the bulk of a transparent solid: confined microexplosion and void formation
Eugene G Gamaly,Saulius Juodkazis,Koichi Nishimura,Hiroaki Misawa,Barry Luther-Davies,L. Hallo,Philippe Nicolai,Vladimir Tikhonchuk +7 more
TL;DR: In this article, a femtosecond laser pulse interaction inside a bulk of transparent media (sapphire, glass, polymer) is studied, which leads to the drastic transformations in a solid resulting in a void formation inside a dielectric.
