  • Description
  • Features

HNLF series is designed to maximize fiber nonlinearity and minimize optical loss, which makes such fibers optimal for constructing highly efficient Raman lasers and amplifiers, dispersion compensators (i.e. for the 2 µm spectral region required for Tm-doped fibers) and various non-linear devices. Non-standard HNLF, including fibers with the core NA>0.6 (pure GeO2-doped fiber core) are available on request.

Other parameters including core NA > 0.6 (pure GeO2 core) are available on the request
