Check List for Rare-earth-doped Fibers

Click here to see a check list before buying such products!
  • 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?

Also have a look at the check list for general fibers and for double-clad fibers.
