Disk lasers optimize quality and reduce production costs

Our laser systems are preferentially employed for laser precision cutting of medical implants and equipment. Aside from miniaturization, the quality requirements are growing significantly in laser cutting towards surface finish, material changes and post processing complexity.

Due to its physical properties the use of disk laser provides decisive advantages in various production processes such as cutting, drilling, structuring or welding of implants or medical equipment. As such, aside from the excellent beam quality and the very good focussing of the beam, the fine pulse to pulse stability and the required pulse energy particularly in processing of metals and metal alloys such as stainless steel, INOX, nickel titanium, tantalum, cobalt chrome etc are the crucial prerequisites for the constant high quality of the results. Because of the significant reduction of the burr formation and the reduced tapering of the cutting surfaces the post processing tasks are massively cut back which saves both time and costs.

The Prenovatec disk laser is delivered in Q-switch mode with the latest control technology and optional external beam delivery and monitoring optics. Constant pulse characteristics, evenly remaining beam quality and constant laser power output are the requirements for the reliability of these laser systems.

In medical implants and stents cutting kerfs of 8 µm in 100 µm thick metals or metal alloys can be achieved. The good focussing also allows the processing of tubing with diameters under 200 µm without damaging the opposing inner tube walls. Significantly reduced heat affected zones hardly change the micro structural properties of the material subsequent to the laser processing.

The advantages of the disk laser in micro cutting at a glance:

•   Cutting kerfs < 10µm possible
•   Virtually no heat affected zones HAZ
•   Cutting without any burr formation
•   High pulse energies
•   High pulse to pulse stability
•   High cutting speeds
•   Smallest beam entry diameters
