The laser has a very short pulse duration which enables it to machine almost any type of material from glass to hardened steel and plastics. As the pulse duration of the laser is shorter than the conduction time of the material, there is no heat signature from processing. The material removal is from solid to vapor, often referred to as “cold ablation”, which provides the highest quality machining and offer unique machining capabilities.
These disc-based femtosecond lasers offer sub-400 fs pulses, plus best-in-class beam quality and peak power. The result is in an extremely high-quality cold ablation cutting process, rather than a melt ejection process.
Therefore, the finished cut requires minimal post processing. In the past, femtosecond lasers were considered too slow for commercially viable laser cutting operations. However, recent studies that have evaluated cutting time per part and post processing steps have demonstrated that the return on investment for a disc femtosecond laser machine can be realized in as little as 12 months, especially for high-value components.
