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.

Preparation of high-quality three-dimensional microstructures on polymethyl methacrylate surfaces by femtosecond laser micromachining and thermal-induced micro-leveling

Optics and Laser Technology, 2022
As a maskless method, femtosecond (fs) laser micromachining has been used to fabricate microstructures on polymethyl methacrylate (PMMA) substrates, but the fs laser ablation promotes the formation of pores and redeposited debris, generating high surface

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 ...
