Where to Buy 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.

Exail (formerly iXblue) offers a wide range of specialty optical fibers for lasers and amplifiers. We master erbium, erbium/ytterbium, ytterbium, thulium, holmium, thulium/holmium, neodymium, dysprosium, and phosphorous gain media. PM version are available, and Large Mode Area (LMA) or Very Large Mode Area (VLMA) versions as well. Depending of the requirement, single clad fibers are available for core pumping, double clad fibers for cladding pumping. Triple clad and all-glass structures are also available.

Fibercore offers a range of double-clad fibers including low index double-clad passive fiber providing high power handling capability with 1060 nm and 1550 nm variants, as well as all-silica double-clad passive fiber which combines both single-mode and multimode characteristics providing outstanding power handling over a full range of environmental conditions.

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.
