Product description

A multimode combiner for 2 µm, available in a 6+1x1 configuration with a signal feed-through fiber and a dual clad output fiber. G&H proprietary manufacturing techniques allow the precise fusion of multimode pump fibers to an SM signal feed-through fiber and a dual clad output fiber providing high coupling efficiency over a wide pump wavelength range.

G&H power combiners can be fabricated from a range of industry standard multimode fibers allowing ease of splicing to commercially available laser diodes. Custom options cover large mode area (LMA), large diameter (LDF) and Active signal feed-through fibers and are available on request.
