Nonlinear photonic crystal fibers

Optimized for supercontinuum generation and nonlinear wavelength conversion, our nonlinear photonic crystal fibers offers a unique combination of tailored dispersion profile and a very high nonlinear coefficient. 

We offer single-mode supercontinuum fibers optimized for all major pumping laser wavelengths. The majority of our nonlinear fibers are available with hermetically sealed ends and FC/PC connectors. In addition, our most popular PM supercontinuum fiber for 800-nm-range pumping are available as in the femtoWHITE devices in which the fibers are mounted in a metal housing with sealed cleanable end-facets.  If you are looking for a turnkey supercontinuum source, please check our SuperK supercontinuum laser products and accessories section.
