Photonic jet: key role of injection for etchings with a shaped optical fiber tip
Robin Pierron, Julien Zelgowski, Pierre Pfeiffer +2
We demonstrate the key role of the laser injection into a multimode fiber to obtain a photonic jet (PJ). PJ, a high concentrated propagating beam with a full width at half maximum…

Etching of semiconductors and metals by the photonic jet with shaped optical fiber tips
Robin Pierron, Sylvain Lecler, Julien Zelgowski +3
The etching of semiconductors and metals by a photonic jet (PJ) generated with a shaped optical ber tip is studied. Etched marks with a diameter of 1 micron have been realized on s…

Photonic jet: direct micro-peak machining
Robin Pierron, Pierre Pfeiffer, Grégoire Chabrol +1
We report on the rst evidence of direct micropeak machining using a photonic jet (PJ) with nanosecond laser pulses. PJ is a high concentrated propagative light beam with a full wid…
