Not only a high average power, which allows to cut few cm metal sheets, but also a high beam quality which is required for precise cutting (like medical stents or battery industry) brings many advantages over existing techniques in cutting industries.
Focusing a single mode beam to very small spot sizes which results in extreme power densities makes single mode fiber lasers a perfect choice for thin metal cutting with smallest possible kerf.
Additionally, the pulsed-mode operation of quasi-CW lasers minimizes thermal effects and heat accumulation, which plays a critical role in micromachining applications. High energy pulses help to cut thick high-reflectivity materials at lower average power.
The most important benefits of fiber laser cutting are:
- Precision and repeatability of high-quality cuts
- Non-contact process (no tool wearing like in mechanical process and no consumables like in plasma or waterjet)
- High speed, scalable process
- Reduced cost of ownership due to maintenance-free operation and production yield
- Possibility to cut high reflection material due to high absorption of 1 mic wavelength
- Variety of output cable lengths and connectors for easy automation
