LOHJA, Finland -- Liekki, a leading supplier of highly doped optical fibers, has developed a new LMA erbium double clad fiber.

Liekki blazes new ground with a highly-doped erbium double clad (Er-DC), large-mode-area (LMA) fiber Er60-20/125DC. This fiber features high erbium concentration for efficient absorption, large 20µm core with low NA of 0.07 supporting good beam quality, and 125µm octagonal-shaped cladding for ease of use. The fiber demonstrates >30% slope efficiency with 980nm pumping with efficient lasing bandwidth extending up to 1.6µm.

Mikko Söderlund, Fiber Product Manager, says "Er60-20/125DC clearly demonstrates the capabilities and quality of the DND technology – this fiber features high concentration, large core/clad ratio, low clustering and low background losses, a combination which is unreachable with conventional processes. It opens up completely new possibilites in the eye-safe wavelength region. We are excited about this first release of the Er-DC product family and look forward to further leverage and develop this core platform into other core/clad ratios and variants like polarization maintaining and all-glass fibers, following our customer's requirements".
