Toptica_FemtoFiber pro

FemtoFiber pro IR

  • Ultrafast fiber laser @ 1560 nm
  • Short pulse (<100 fs) with highest power (>350 mW)
  • SAM mode locking, PM fiber based MOPA system
  • Robust and reliable design, push button operation
  • Compact footprint < Letter/A4 format

The FemtoFiber pro IR is the base version of TOPTICA’s FemtoFiber pro series. It comprises a very robust SAM mode-locked master-oscillator with a core-pumped power amplifier in one single box, having highest output power for fiber lasers on the market.  The system benefits from exclusive use of polarization maintaining fiber components and allows optimizing the pulse characteristics to individual needs by a built-in motorized prism compressor.
