FemtoFErb 2000

Compact 2 µm seed laser source

  • Supercontinuum source using highly nonlinear fiber
  • Broad emission spectrum > 100 nm @ 1970 nm
  • Alignment-free all-fiber setup, use of PM fibers only
  • SAM mode-locking technology
  • Compact design: optics and electronics just in one box

The FemtoFErb 2000 laser is a very robust all fiber-based femtosecond laser system with excellent amplitude and frequency jitter parameters. A more than 100 nm wide-spanning supercontinuum is generated with a highly nonlinear fiber. This laser unit can be used as a high reliable and cost-effective seed source for e.g. Thulium or Holmium based amplifier systems.

  • Options


    The FemtoFiber pro SwitchBox is a small tool for quick starters. It provides all switches, supply and status lines to run a PicoFYb as a stand-alone system without integration environment and therefore is especially recommended for single-system users.

  • Applications
    • Seeding for Thulium/Holmium amplifier systems
