ZBLAN-DCFF (Double Cladding Fluoride Fiber) is very useful
for high power fiber lasers and amplifiers with unique wavelengths such
as 1.3um、1.46um、2.3um, and 2.8um. Especially, our octagonal
cladding DCFF manufactured by unique fiber making process benefits superior
pump absorption efficiency and easy fiber handling.
