Femtosecond laser-induced selective etching
...of nanometers. A FemtoLux supplies the pulses for both examples here. A movable bistable switch was made in fused silica with 20 µm arm widths, and through-glass vias of various diameters were etched taper-free in the same material. One comes from micromechanics, the other from semiconductor fabrication. Manufacturing examples Femtosecond...
Bottom-up milling of glass
...through the backside and high aspect ratio geometries can be formed in glass. The FemtoLux GHz burst function combined with bottom-up milling raises process throughput. Precise, flexible control of the burst energy and the number of pulses in the burst sets the thermal stress generated in the glass substrate. With...
Thin glass cutting
Thin glass cutting Glass substrates thinner than 0.5 mm are fragile and crack readily under thermal load. The ultra-short pulse duration of a femtosecond laser keeps thermal accumulation low, which is what allows cutting, milling and drilling at this thickness. The FemtoLux allows processing parameters to be tuned to each...
Femtosecond processing of GaAs in air and water
...were milled in GaAs with a FemtoLux laser at 1030 nm and 900 fs, at repetition rates of 10, 50 and 200 kHz. Under a layer of water the trench depth nearly doubled, from 58 µm in ambient air to 105 µm, and the band of redeposited debris narrowed from...
Metal surface texturing
...shifts; tribological performance improves; and bacterial adhesion drops. FemtoLux is used for this work. It textures master molds, aluminum among them, with detailed surface geometry. It also produces antibacterial surfaces: tuning the pulse energy adds nano-features on top of a coarser pattern, and the resulting hierarchical texture markedly reduces bacterial...
Metal milling in MHz burst mode
...MHz burst mode splits the high-energy pulse into sub-pulses, so the optimum fluence is reached without that penalty. In a study by A. Žemaitis et al., a FemtoLux was used to optimize machining of aluminum, copper and stainless steel by milling 110 cavities in a single sample, varying the repetition...

Dementjev, Ekspla (2020), https://ekspla.com/wp-content/uploads/Open-Publications/AppNotes-ND-FemtoLux3-in-microscopy.pdf. FemtoLux 3 laser was used as an illumination source in the wide-field second harmonic generation (SHG) microscope. Relatively high laser pulse energy at a medium pulse...

Polymer cutting and milling
...edge stays clean. FemtoLux suits this work on two counts. Its pulse duration is short enough to process polymer without a significant thermal load, and its 4 MHz repetition rate carries the throughput, with scanning speeds of several meters per second. A 10 mm circle is cut from polymer film...
