In recent years, ultrashort femtosecond laser technology has been introduced, which produces pulses that leave no thermal fingerprint on the part. Microsecond fiber lasers have been used successfully for medical device applications in hypo tube and stent cutting for many years. While precise and fast, the downside has been that the parts require a number of post-processing operations after they are cut, which adds significantly to part cost and can also damage mechanically delicate parts. In recent years, ultrashort femtosecond laser technology has been introduced, which produces pulses that leave no thermal fingerprint on the part. These disk-based femtosecond lasers offer sub-400fs pulses, plus best-in-class beam quality and peak power that enable an extremely high-quality cold ablation cutting process rather than a melt ejection process. Therefore, the resulting cut requires minimal post-processing and the smaller beam size allows machining of very fine details. The process works especially well for production of such medical devices as catheters, heart valves, and stents, as well as in other medical glass cutting and marking applications and in 3D structuring of ceramic mate...
