LASER ABLATION

Laser ablation based on ultra-fast interaction between material and femtosecond laser irradiation allows "cold processing" with minimal thermal effects and superb cut quality without damaging the surrounding material. Almost any material can be processed: metals, polymers, glass, even paper (banknotes, for example).

Examples

Holes in hard metal
Ablation speed – up to one hole of 30 µm in diameter and 18µm out diameter in 50 ms.

Square holes with rounded corners
Pitch between holes substantially smaller that the size of the hole. Spaces are thin and straight, ablation edges are clear, minimal thermal influence.

Surface structuring
The surfaces created with fs pulses can be easily made both repelling and adhering, playing into needs of basically any application
