Ultrafast Thulium (2μm)
The quality of any laser application crucially depends on the performance of the driving light source, i.e. the laser itself. In addition, most applications ask for more and more average power from the laser source to be cost-effective or sensitive enough.
AFS‘s ultrafast fiber lasers are characterized by an outstanding performance combined with flexibility and maximum stability. We have been selling high-power fiber lasers for more than a decade now and continue to push the boundaries of what is possible. The newest model Thulium-300 offers unprecedented ultrafast average power at 2µm central wavelength in combination with a very high pulse energy.
All essential parameters are software controlled and can be tuned over a wide range, making them an extremely valuable tool in many applications.
