Fluoride Fibers

Supercontinuum generation fibers

Thanks two their non linear properties, combined to their high transparency from UV up to mid-IR, fluoride fibers are widely used for supercontinuum generation:

In 2006 the first supercontinuum generation, extending from 0.8 up to 4.5µm was demonstrated from LVF ZBLAN fluoride fibers by Xia et al. [ref].

ZFG and IFG fluoride fibers are integrated in the commercial supercontinuum source Electro-MIR 4100 and Electro-MIR 4800, developed in colaboration with LEUKOS.

Our two star fibers for supercontinuum generation are:

1) ZFG SM [2.55] 8.5/125
