FemtoFiber pro SCIR – supercontinuum

  • Broadband infrared fiber laser source 980 - 2200 nm  
  • Octave spanning continuum generated by HNLF
  • SAM mode locking, PM fiber based MOPA system
  • Compact footprint, < Letter/A4 format
  • Robust and reliable design, push button operation

The FemtoFiber pro SCIR comprises a very robust MOPA system with an octave-spanning supercontinuum generation (980 – 2200 nm) in one single box. The broadband continuum emission is generated by a Highly-nonlinear fiber (HNLF) and can be altered by the built-in motorized prism compressor, for an optimization to individual needs.
