Swisstec AG is manufacturing high-end laser micromachining systems for precision cutting, drilling and welding of complex and intricate work pieces - applications found typically in the medical device and aerospace/defence industries. Especially in the field of stent cutting, Swisstec AG offers a complete palette of compact, high performance tube cutting systems enabling state of the art industrial stent cutting at high speed.
In future, the cutting systems can be equipped with femtosecond laser sources, which is the core competence of High Q Laser Production GmbH.
The big advantages of the femtosecond laser are its short interaction time with the material and high peak intensity. Pulse durations in the femtosecond time scale enable what is called “cold cutting” because material removal occurs faster than significant heat conduction. This offers cutting without any melting or burr formation at the edges reducing the effort of further treatments of the stents to a minimum.
The high intensities provided by femtosecond laser pulses enables multiphoton absorption processes which means that nearly every material is absorbing the laser light. So with this fscutting system every material can be processed with highest precision, no matter if its metallic, ceramic or even polymer based (e.g. bioresorbable polymers).
High Q Laser is a world leading supplier of all-dioded-pumped solid-state ultrafast lasers, i.e. femtosecond and picosecond lasers for scientific, medical and industrial markets.
Based on the technologies of direct diode pumping and semiconductor saturable absorber mirrors (SESAMs), the lasers are extremely compact and easy-to-use turn-key laser systems.
