About FEMTOsecond LASER

FEMTOsecond LASER μ-machining is the most advanced LASER technology to process a wide range of materials. Thanks to very low heat diffusion time (< 300 fs), thermal effects are avoided. High energy density improves surface and geometries quality, while a high repetition rate ensures excellent productivity.

Function

The FEMTOsecond LASER technology is a perfect match for all industries requiring the highest precision without compromising quality and productivity.

Miniaturized components are used in all kind of devices. Several applications – e.g. in the electronics or MedTech world – are not imaginable without very small and tiny parts. Thus, this requires new ways to produce and manufacture these parts. With FEMTO LASER μ-machining there are various processes possible like drilling, cutting and turning. It's compatible with almost all materials that are otherwise very difficult to machine with conventional tools.

With each FEMTOsecond LASER pulse that hits the work-piece, a small amount of material immediately vaporizes. The material removal occurs in a controlled manner leading to no damage, burrs or any negative influences to the material integrity.

What means FEMTO?

A FEMTO-LASER is a Laser which emits optical pulses with a duration well below 1 ps, i.e.,in the domain of femtoseconds (1 fs = 10⁻¹⁵ s = Onequadrillionth of one second). It thus also belongs to the category of ULTRAFAST LASERS or ULTRASHORT PULSE LASERS.
