Processing of polymer

Femtosecond lasers, with their very short pulse durations, offer a solution for low heat conductivity of polymers by enabling the precise machining of them while preserving process quality.

Photopolymerization

Photopolymerization is a versatile technique in fabricating complex micrometer size 3D structures by employing femtosecond lasers in selectively solidifying resin. These 3D polymer structures with basically any shape and thickness are applied in tissue engineering, electronics, optics and microfluidics.

Compact low-power femtosecond laser FemtoLux 3 fits photopolymerization application perfectly. Due to short pulse duration of 300 fs the photopolymerization can be initiated via two-photon absorption process, allowing in-volume solidification of resin, enabling any geometry formation. Additionally, together with 3 W of average power and maximum repetition rate of 10 MHz, the photopolymerization process speed can be maximized by taking advantage of fast scanning optics.
