Toward 3D Printing of Pure Metals by Laser-Induced Forward Transfer.

TL;DR: Copper and gold pillars are manufactured with a resolution below 5 μm and a height up to 2 mm, using laser-induced forward transfer to create and eject liquid metal droplets and the solidified drop's shape is discussed as a function of the laser energy.
Journal ArticleDOI

Electro-optic and Acousto-optic Laser Beam Scanners

TL;DR: In this article, the principles of operation of electro-optical or acousto-optic deflectors and AODs are described and the characteristics, properties and the (dis)advantages of EODs, when compared to mirror-based mechanical de-∆ectors, are discussed.
Journal ArticleDOI

Effect of surface roughness on the ultrashort pulsed laser ablation fluence threshold of zinc and steel

TL;DR: In this paper, the single and multiple pulse laser ablation threshold of zinc and steel at picosecond laser pulse duration is studied as a function of initial surface roughness at laser wavelengths of 515 and 1030 nm.
Journal ArticleDOI

Ejection Regimes in Picosecond Laser-Induced Forward Transfer of Metals

TL;DR: In this paper, the authors present visualizations of ejection events at high-spatial (submicrometer) and high-temporal resolutions, for picosecond LIFT of copper and gold films with a thickness 50
Journal ArticleDOI

Picosecond-pulsed laser ablation of zinc: crater morphology and comparison of methods to determine ablation threshold.

TL;DR: A comparative analysis on the determination of the ablation threshold using three methods, based on ablated diameter, depth and volume is presented along with associated incubation coefficients, found that both the fluence threshold and energy penetration depth show lesser degree of incubation for multiple laser pulses.
