Where to Buy Double-clad Fibers

Before You Buy: Learn About Double-clad Fibers

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.

More general product categories: rare-earth-doped fibers, specialty fibers

Related product categories: triple-clad fibers, large mode area fibers, fiber optics

Related product category: fiber optics

With its comprehensive resources, RP Photonics helps you to well prepare purchase decisions:

Some aspects to consider before buying double-clad fibers: core and cladding diameter, cladding shape, numerical aperture of core and cladding, type of density of laser-active dopant, pump absorption efficiency, power handling capacity, protective coating, thermal stability, availability of spectroscopic data, badge-to-badge consistency.

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.
