Where to Buy Rare-earth-doped Fibers
Active fibers are available with various rare earth dopants such as Yb, Nd, Er, Pr and Tm. They are mostly used for fiber lasers and amplifiers.

Check List for Rare-earth-doped Fibers
- What kind of laser-active dopant do you need – Er3+, Yb3+, Nd3+, Tm3+ or anything else?
- Can it be a kind of silica fiber, or do you require some specialty glass, e.g. a fluoride fiber?
- What doping concentration do you need? Alternatively, manufacturers often specify the absorption at some given wavelength(s).
- What is the fiber's quality? Is the power conversion efficiency reduced by quenching effects and the like?
- What is the effective mode area or mode radius? (There are special large mode area fibers.)
- (For single-mode fibers, the core diameter and numerical aperture are usually not relevant, if the mode area is known.)
- (The propagation losses are usually not very relevant, except if an unusually long length of fiber is used.)
- For double-clad fibers: what is the diameter and numerical aperture of the pump cladding? Is the pump cladding circular, elliptical or D-shaped?
- How tight bending is possible, before the bend losses become too high?
- How much optical average power can the fiber tolerate? (Additional properties at the launch end may still occur if too much power gets to the coating.)
- What is the outer fiber diameter with and without protective coating?
- What is the coating material? Is it a standard material which can be removed with a usual fiber stripper?
- Can the fiber be cleaved with a standard fiber cleaver? (Fluoride fibers, for example, have quite different mechanical properties than silica fibers.)
- Are there fiber couplers available for combining pump and signal inputs, or for separate pump and signal at the end?
