LARGE MODE AREA FIBERS
The selection of Crystal Fibre 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 have to 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. The fibers can be spliced to standard single mode fibers or directly connectorized with standard FC/PC connectors or SMA 905 high power connectors.
The fibers are also available in polarizing and polarization-maintaining versions.

FEATURES:
- Handles very high average power as well as high peak power
- Low nonlinearities
- Low fiber loss
- Endlessly single mode operation - no higher order mode cut-off
- Mode field diameter is wavelength independent
- Available with core sizes from 5 to 35 microns
SELECTION GUIDE:
In case of high power delivery it is important to choose the largest feasible
core size. On the other hand, single mode fibers will become bending sensitive
at some short wavelength edge - the larger the core size, the longer wavelength
the bend loss induced edge will have.
Please refer to the below chart in order to choose the most appropriate fiber
for a given wavelength.
For more specific bend loss and attenuation level information, please refer
to individual datasheets.
Please note that any of the above fibers will be excellent for long wavelength
guidance (no long wavelength bending loss edges), though you would typically
benefit from moving to a larger core size.
APPLICATIONS:
- High power delivery- Short pulse delivery
- Mode filtering
- Laser pigtailing
- Multiwavelength guidance
- Broadband interferometry
