We report on the laser ablation of composite prismatic structures using a vacuum ultraviolet (VUV) 157 nm F2 laser. Polycarbonate and CR-39 substrates have been intentionally seeded with silver wires and silicon carbide whiskers respectively. The seed particles remain attached to the underlying substrate after laser ...

. For example, boron carbide (B4C) is an extremely hard material used in aircraft gyroscopes, silicon carbide at different length scales, depending upon the synthesis conditions. The initial ablation product comprises, it is very difficult to synthesize a single phase of only R-C3N4 or -C3N4. Disappointingly, ...

Femtosecond lasers have proved to be effective tools for micromachining silicon carbide material. In the drilling process, however, when the debris around the hole was not removed efficiently, the depth of hole would not increase further. In this paper, alcohol-assisted photoetching of 6H silicon carbide was ...
