Where to Buy Large Mode Area Fibers

Optical fibers with particularly large mode areas are useful particularly for high-power fiber amplifiers and lasers, because they have reduced nonlinear effects.

Check List for Large Mode Area Fibers

Click here to see a check list before buying such products!
  • What is the effective mode area or mode radius? (There are special large mode area fibers.)
  • Is the fiber truly single-mode, or does it support a few modes? (In the latter case, careful launching maybe important for the output beam quality, and certain instabilities can occur for operation with very high average output power.)
  • What are the propagation losses (in dB/km)?
  • Does it need to be polarization-maintaining?
  • How tight bending is possible, before the bend losses become too high?
  • How much optical 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?

For active fibers, also look at the check list for rare-earth-doped fibers.

large mode area fibers

The selection of Crystal Fiber Large Mode Area fibers covers a range of fibers for diffraction limited high power delivery. The very large mode area enables high power levels without nonlinear effects or material damage. With standard technology you must trade large mode areas for single-mode operation, but the Crystal Fibre Large Mode Area fibers provide single mode operation in a large wavelength range – endlessly single mode operation.
