Where to Buy Double-clad Fibers

Double-clad fibers are active optical fibers with an additional pump cladding that accepts pump radiation with low beam quality. They are widely used in high-power fiber amplifiers and lasers, enabling efficient energy transfer from the pump light to the highly coherent laser light. They are thus acting as brightness converters.

double-clad fibers

LVF offers a range of rare-earth doped double cladding single-mode and multimode fluoride fibers for high power laser generation. Most of them exhibit a double D-shape on the first cladding in order to improve the pump absorption.

Undoped double cladding single-mode and multimode fluoride fibers are also available.

double-clad fibers

Our ytterbium-doped double-clad fibers offer the largest single-mode cores in the world. The high numerical aperture for the pump core/inner cladding lets you pump with high efficiency, even with inexpensive or high-power broad-area emitting pumps. The single-mode signal travels in the large mode area to give high power levels and prevents nonlinearities. Need it packaged? Choose one of our aeroGAIN-ROD or aeroGAIN-BASE modules.
