MULTIMODE POWER COMBINER WITH SIGNAL FEED-THROUGH FOR 2 µM OPERATION
6+1x1 Tapered Fiber Bundle
Gooch & Housego combiners provide a high efficiency means of combining light from several multimode sources into one fiber.
G&H proprietary manufacturing techniques allow the precise fusion of input fibers around a central signal feed-through fiber and a dual clad output fiber providing high coupling efficiency over a wide pump wavelength range.
Available in a standard (6+1)x1 configuration, the combiner can be fabricated from a range of industry standard and customized fibers for ease of splicing to commercially available laser diodes and fiber applications.
Custom options cover large mode area (LMA) signal feed-through fibers, dual clad output fibers and port count/configurations and are available on request.
Please contact the sales team for further information.
