FemtoFErb 1950


  • Frequency shifted Er-doped fiber laser
  • Short pulse emission < 100 fs @ 1950 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 1950 laser is a very robust all fiber-based femtosecond laser system with excellent amplitude and frequency jitter parameters. A more than 50 nm wide-spanning frequency shifted output spectrum centered at 1950 nm 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.
