Journal ArticleDOI
Microdeposition of metal and oxide structures using ultrashort laser pulses
Ioanna Zergioti,Sakellaris Mailis,Nikolaos A. Vainos,Pagona Papakonstantinou,C. Kalpouzos,Costas P. Grigoropoulos,Costas Fotakis +6 more
TL;DR: In this article, a one-step fabrication of binary-amplitude and multilevel optical diffractive structures on glass and silicon substrates is performed, where the superior quality of the results allows the direct, one-stage fabrication of Binary Amplitude (BAM) and Multilevel Optical Diffractive (MOW) structures.
Journal ArticleDOI
Microdeposition of metals by femtosecond excimer laser
Ioanna Zergioti,Sakellaris Mailis,Nikolaos A. Vainos,Costas Fotakis,Shaochen Chen,Costas P. Grigoropoulos +5 more
TL;DR: In this article, a KrF excimer laser (λ=248 nm) having 500-fs pulse duration is coupled to a high-power image projection micromachining workstation.
Journal ArticleDOI
Microfabrication by UV femtosecond laser ablation of Pt, Cr and indium oxide thin films
TL;DR: In this article, the authors demonstrate the direct deposition of Pt, Cr and In2O3 microstructures on glass using an ultrashort excimer laser pulse ablating the source film at the quartz/film interface and results in the forward-transfer deposition of material onto the nearby glass receiver.
Journal ArticleDOI
Ti:sapphire planar waveguide laser grown by pulsed laser deposition.
A.A. Anderson,Robert W. Eason,L.M.B. Hickey,Miroslav Jelinek,Christos Grivas,D.S. Gill,Nikolaos A. Vainos +6 more
TL;DR: The lasing performance of a waveguiding layer of Ti:sapphire, of ~12-mum thickness, grown by pulsed laser deposition from a 0.12-wt.% Ti(2)O(3) Ti:Sapphire single-crystal target onto an undoped z-cut sapphire substrate is documented.
Journal ArticleDOI
Modern technology in artwork conservation: a laser-based approach for process control and evaluation
TL;DR: The present work includes a laser-based methodology for the cleaning of artworks, with emphasis on the preservation of their structural integrity and identity, and selected examples of this type of applications in a carefully considered methodology are presented.
