Non-reciprocal femtosecond laser micromachining

2008 Conference on Lasers and Electro-Optics, 2008
The authors demonstrate both experimentally and theoretically that in a non-centrosymmetric crystal modification of the material can be different when femtosecond laser beam propagates in opposite directions. Our result presents the first evidence of non-reciprocal photosensitivity.

Titanium micromachining by femtosecond laser

Optics and Lasers in Engineering, 2012
Abstract The ultimate goal of this research was to characterize the ablation depth with respect to pulse energy, translation speed, and consecutive passes in order to obtain the parameters to have smooth microchannel surfaces. A logarithmic dependence of the channel depth on the laser pulse energy was observed with two different distinct ablation ...

Femtosecond Laser Micromachining

2013
Ultrashort laser pulses with durations in the femtosecond range up to a few picoseconds provide a unique method for the structuring of practically all materials with high precision and minimal thermal and mechanical influence of the surrounding. Due to the high intensities obtained in the focal volume even at moderate pulse energies not only surface ...

Femtosecond laser micromachining in transparent materials

Nature Photonics, 2008
Femtosecond laser micromachining can be used either to remove materials or to change a material's properties, and can be applied to both absorptive and transparent substances. Over the past decade, this technique has been used in a broad range of applications, from waveguide fabrication to cell ablation.
